The crankshaft position sensor (CPS) is one of the key elements of the engine management system Škoda Rapid. Its malfunction leads to engine malfunctions, difficult starting or a complete stop of the car. Despite its simple design, this sensor is responsible for synchronizing fuel injection and ignition, so any failures are critical for engine operation 1.2 TSI, 1.4 TSI and 1.6 MPI, installed on Rapid different generations.
In this article we will look at how recognize a faulty DPKV according to symptoms and error codes, where it is located under the hood, how to check it with a multimeter and replace it without contacting service. We will also provide current prices for original and similar sensors, and at the end we will answer frequently asked questions from owners Škoda Rapid about the intricacies of diagnosis.
Where is the crankshaft sensor located on the Škoda Rapid?
On all modifications Škoda Rapid (including restyled versions 2017+) the crankshaft sensor is installed in the same place - on oil sump from the gearbox side. Exact location:
- 🔧 Engines 1.2/1.4 TSI (CZDA, CZTA, CWVA): The sensor is attached to the cylinder block on the right (in the direction of travel) next to the flywheel. Access to it is possible from below the car or through a technological hole in the fender liner.
- 🔧 Engines 1.6 MPI (CWVA, CPWA): DPKV is located on the front of the cylinder block, just above the timing drive. To replace, you will need to remove the belt guard.
Visually, the sensor is a cylindrical body with a wiring connector and a metal core. It is attached to one M6 bolt (less often - M8), so a key for dismantling is enough 10 mm or heads with extension. It is important not to confuse it with camshaft sensor, which is located on the cylinder head.
How to distinguish DPKV from camshaft sensor?
The crankshaft sensor on the Škoda Rapid always has a longer housing (about 8–10 cm) and is located closer to the flywheel. The camshaft sensor is shorter (5–6 cm) and is attached to the cylinder head. Also, the DPKV connector is usually marked G28 (for VAG), and on the camshaft sensor - G40 or G163 (depending on engine model).
On some versions Rapid (for example, with a motor 1.4 TSI ACT) the sensor can be hidden under a plastic cover - it must be removed by snapping 4 latches. Before dismantling it is necessary disconnect the negative terminal of the batteryto avoid ECU errors.
Signs of a faulty crankshaft sensor
A faulty DPKV manifests itself differently depending on the nature of the failure. On Škoda Rapid most common symptoms:
- ⚠️ Engine won't start or stalls immediately after starting - the ECU does not receive a signal about the crankshaft position and blocks the fuel supply.
- ⚠️ Floating speed at idle speed (from 500 to 1500 rpm) - the sensor transmits an unstable signal.
- ⚠️ Power Loss and “failures” during acceleration - the ECU goes into emergency mode, limiting the speed to 3000–4000.
- ⚠️ Detonation under load - incorrect ignition timing due to synchronization failures.
- ⚠️ Check Engine lights up 2-3 seconds after starting and does not go out.
A critical feature for the Škoda Rapid: if the sensor fails completely, the engine may only start after 3–5 attempts and the immobilizer indicator (key with an exclamation mark) will light up on the dashboard. This is due to the fact that the Bosch ME7/MED17 ECU installed on TSI engines blocks the fuel injectors when there is no signal from the DPKV.
On engines 1.6 MPI the malfunction manifests itself less aggressively: it is usually difficult hot start and twitching when driving at low speeds. Unlike TSI, here the ECU does not completely block the engine, but significantly worsens its dynamics.
- Only when errors occur
- Once a year during maintenance
- Independently every 10,000 km
- Never checked
DPKV error codes for Škoda Rapid (OBD-2)
When scanning a car with a diagnostic scanner (for example, VCDS, Launch X431 or even budget ELM327) a malfunction of the crankshaft sensor is manifested by the following codes:
| Error code | Description | Probable Cause | Criticality level |
|---|---|---|---|
P0335 |
Crankshaft position sensor circuit malfunction | Wire break, contact oxidation, short circuit | ⚠️⚠️⚠️ High |
P0336 |
DPKV signal range/performance out of normal range | Sensor wear, contamination, mechanical damage | ⚠️⚠️ Average |
P0337 |
Crankshaft sensor signal low | Poor contact in the connector, damage to the shielding braid | ⚠️⚠️ Average |
P0338 |
High DPKV signal level | Short circuit to +12V, ECU malfunction | ⚠️⚠️⚠️ High |
P0339 |
Intermittent sensor signal | Poor sensor fixation, fastening play, contamination | ⚠️ Low |
On Škoda Rapid with engines 1.2/1.4 TSI errors P0335 and P0336 often accompanied by additional codes for the ignition system (P0300 - multiple misfires). This is due to the fact that the ECU loses synchronization and incorrectly calculates the moment of spark formation.
On motors 1.6 MPI typical mistake P0339, which occurs due to loosening of the sensor or metal shavings getting onto its end. In this case it is enough clean the sensor and securely tighten the fastening bolt.
⚠️ Attention: If after resetting errors (for example, through VCDS → 01-Engine → Clear DTC) codes appear again, this clearly indicates a malfunction of the sensor or its circuit. Don't ignore repeated errors - this can lead to catalyst overheating due to incorrect fuel injection.
How to check the crankshaft sensor on a Škoda Rapid?
You can diagnose DPKV yourself using multimeter (in ohmmeter/voltmeter mode) or oscilloscope (for advanced users). Let's consider both methods.
Checking with a multimeter
To test the sensor winding resistance:
- Remove the connector from the sensor by pressing the lock.
- Switch the multimeter to resistance measurement mode (
200 Ohm). - Connect the probes to the sensor terminals (polarity is not important).
Normal values for Škoda Rapid:
- 🔹 Original VAG sensor (03C 905 163):
550–750 Ohm. - 🔹 Analogs (Bosch, Hella, Febi):
500–800 Ohm.
If resistance 0 ohm (short circuit) or ∞ (break), the sensor must be replaced. Also check wiring integrity from the sensor to the ECU: the wires near the connector often fray.
Checking with an oscilloscope (advanced method)
To analyze the signal you will need USB oscilloscope (for example, Hantek 6022BE) or a diagnostic scanner with an oscilloscope function. Connect to the signal wire of the sensor (usually the middle pin in the connector) and start the engine. A normal signal should look like sinusoid with amplitude 0.5–2 V and clear peaks when the crankshaft rotates.
Signs of a malfunction on the oscillogram:
- 📉 Noisy signal - indicates damage to the shielding braid.
- 📉 Low amplitude (less than 0.3 V) - wear of the sensor or too large a gap to the drive disk.
- 📉 Missing pulses — contamination of the sensor end or damage to the disk.
☑️ Checklist before checking DPKV
Checking without tools
If you don't have a multimeter at hand, you can do express test:
- Remove the sensor from the vehicle.
- Inspect its end for metal shavings or chips.
- Shake the sensor next to your ear - if you can hear it inside knocking or rattling, this is a sign of core failure.
Also note gap between sensor and drive disk (must be 0.5–1.5 mm). If the gap is larger, the signal will be weak, which will lead to errors P0336 or P0337.
Step-by-step instructions for replacing the crankshaft sensor
Replacing DPKV with Škoda Rapid takes no more than 20–30 minutes and does not require special skills. You will need:
- 🔧 Key or head on
10 mm(less often -8 mm). - 🔧 Flat blade screwdriver (for removing the connector lock).
- 🔧 New sensor (original or analogue).
- 🔧 Dielectric grease (eg Liqui Moly Electronic-Spray).
Sequence of actions:
- Disconnect the negative terminal of the battery (required!).
- Press the latch and disconnect the sensor connector. If the contacts are oxidized, clean them WD-40.
- Unscrew the sensor mounting bolt with a wrench
10 mm. - Carefully remove the sensor by rocking it from side to side (do not pull on the wires!).
- Clean the seat from dirt and metal shavings.
- Install the new sensor, making sure it is fully seated.
- Tighten the mounting bolt to torque
8–10 Nm(do not overtighten!). - Connect the connector and return the terminal to the battery.
After replacement be sure to clear errors through a diagnostic scanner. If the codes appear again, check:
- 🔹 Correct installation (the sensor must rest against the thrust ring).
- 🔹 Integrity of wiring from sensor to ECU.
- 🔹 Condition of the drive disc on the crankshaft (are there any chips or corrosion).
Before installing a new sensor, apply a thin layer of dielectric grease to its end - this will prevent oxidation of the contacts and improve signal transmission.
⚠️ Attention: On engines 1.4 TSI (CZDA) when replacing DPKV it may be necessary throttle adaptation through VCDS → 01-Engine → Basic Settings → Group 060. Without this, the idle speed may float for 1–2 days.

- 💰 Independent service: 800–1 500 ₽.
Frequently asked questions about the crankshaft sensor on the Škoda Rapid
Is it possible to drive with a faulty DPKV?
No, it's dangerous. On Rapid with engines 1.2/1.4 TSI The ECU blocks the engine from starting or puts it into emergency mode with a speed limit of up to 3000. 1.6 MPI Driving is possible, but with jerks and increased fuel consumption. Long-term operation with a faulty sensor leads to catalyst overheating and failure of spark plugs.
Which sensor is better to choose: original or analogue?
For Škoda Rapid optimal choice - Bosch or Hella. They are 30–40% cheaper than the original, but are not inferior in reliability. Febi and Topran suitable for temporary replacement, but their service life rarely exceeds 30,000 km. Original sensor 03C 905 163 A It lasts 100,000+ km, but its price is justified only with warranty repairs.
Why does the error not go away after replacing the sensor?
The reasons may be as follows:
- 🔹 Errors in the ECU have not been reset (need to be reset via
VCDSor scanner). - 🔹 The wiring from the sensor to the ECU is damaged (check the circuit with a multimeter).
- 🔹 Incorrect gap between sensor and drive disc (must be
0.5–1.5 mm). - 🔹 The ECU itself is faulty (less often, but possible during power surges).
If the problem persists, check master disk status on the crankshaft - sometimes its teeth are damaged and the sensor cannot read the signal.
Is it possible to clean the crankshaft sensor instead of replacing it?
Yes, but only if the problem is contamination of the end. Use isopropyl alcohol or carburetor cleaner (do not use acetone or gasoline!). Clean carefully with a cotton swab without scratching the surface. If the sensor has mechanical damage (cracks, chips) or an internal winding break, cleaning will not help - replacement is required.
How often should the crankshaft sensor be replaced?
DPKV is non-consumable element, and in normal mode it serves the entire life of the vehicle. Replacement is only required if:
- 🔹 Mechanical damage (for example, after an accident).
- 🔹 Short circuit or winding break.
- 🔹 Severe contamination that cannot be removed by cleaning.
If the sensor is working, replace it will not improve dynamics or fuel consumption - This is a common myth.
