Crankshaft sensor on ŠKODA Octavia A5: diagnostics, errors and DIY replacement

Crankshaft position sensor (CPS) on ŠKODA Octavia A5 - one of the key elements of the engine management system. Its malfunction leads to engine malfunctions, difficult starting or a complete stop of the car. Unlike many other sensors, DPKV does not have redundant systems, therefore its failure makes further operation of the machine impossible.

In this article we will look at how to independently diagnose problems with the sensor, what error codes indicate its malfunction, and how to replace it without contacting service. We will place special emphasis on the nuances specific to Octavia A5 with engines 1.4 TSI, 1.6 MPI, 1.8 TSI and 2.0 TDI. We will also provide current prices for original and similar spare parts so that you can estimate the repair budget.

Signs of a faulty crankshaft sensor on an Octavia A5

Symptoms of DPKV failure are often similar to malfunctions of other systems (for example, fuel pump or ignition coils), but there are a number of characteristic featuresthat help narrow your search:

• 🔴 Engine won't start or stalls immediately after starting - the most obvious symptom indicating a lack of signal from the sensor.
• ⚠️ Lights up on the dashboard Check Engineand the scanner shows errors P0335, P0336 or P0016.
• 📉 Floating idle speed or its spontaneous change in the range 500–1500 rpm.
• 🚗 Jerks and dips during acceleration, especially at speeds 60–90 km/h.
• 🔧 Loss of engine power (the car “does not pull”), accompanied by increased fuel consumption.

On Octavia A5 with engines 1.8 TSI and 2.0 TDI faulty DPKV may appear false activation of the ESP stabilization system, since the ECU receives incorrect data about the position of the crankshaft and interprets this as a loss of traction.

It is important to consider that similar symptoms can be caused by:

• 🔌 Damage to the wiring or oxidation of the contacts in the sensor connector.
• 🛢️ Contamination or damage to the reference disk on the crankshaft.
• 🔄 Malfunction of the engine ECU (rare, but occurs on cars with mileage >200 thousand km).

Error codes related to DPKV on the ŠKODA Octavia A5

When connecting a diagnostic scanner (for example, VCDS or ELM327) a malfunction of the crankshaft sensor is manifested by the following codes:

Error code	Description	Probable Cause
P0335	Crankshaft position sensor circuit malfunction	Broken wiring, corrosion of contacts, sensor failure
P0336	DPKV signal range/performance out of acceptable range	Mechanical damage to the sensor, contamination, incorrect clearance
P0016	Inconsistency between the DPKV and camshaft sensor signals	Timing belt misaligned, both sensors faulty
P0339	Intermittent DPKV signal	Poor contact in the connector, damage to the shielding braid

On Octavia A5 with engines 1.4 TSI and 1.8 TSI error P0335 often accompanied turning off the cylinders (errors P0300–P0304), since the ECU cannot correctly determine the timing of injection and ignition. In this case, the engine operates with strong vibration, and the icon may light up on the instrument panel. ESP.

⚠️ Attention: If after resetting the errors they appear again after 5-10 minutes, this almost always indicates mechanical malfunction of the sensor or drive disk. Checking with a multimeter in this case is useless - a visual inspection is required.

Where is the crankshaft sensor located on Octavia A5?

On all modifications ŠKODA Octavia A5 (including facelift) DPKV is located at the bottom of the engine, next to the flywheel. The exact location depends on the type of motor:

• 🔧 1.4 TSI, 1.6 MPI, 1.8 TSI: The sensor is installed on the oil scraper pump cover, to the right of the flywheel (if viewed in the direction of travel). A wiring harness with a connector leads to it.
• 🔧 2.0 TDI: The DPKV is located on the cylinder block, closer to the gearbox. Access to it is difficult due to the exhaust manifold.

For clarity, we provide an example layout diagram 1.8 TSI:

DPKV location diagram on 1.8 TSI

The sensor is indicated by a red circle. It is secured with one bolt (M6) and has a two-pin connector. There is a wiring harness running nearby that often rubs against the engine mounting bracket.

To get to the sensor you will need:

1. Remove the engine protection (if installed).
2. On engines 2.0 TDI — dismantle the air duct and partially move the exhaust manifold to the side.
3. On 1.4 TSI and 1.8 TSI — remove the plastic timing cover (if it interferes).

How to check the crankshaft sensor on Octavia A5?

Diagnosis of DPKV includes three stages: visual inspection, checking with a multimeter and analyzing the signal with an oscilloscope. Let's start with the simplest thing.

1. Visual inspection

Inspect the sensor and its connector for:

• 🔌 Oxidation of contacts (green coating on the plugs).
• 🧲 Mechanical damage sensor housing (cracks, chips).
• 🛢️ Oil stains - indicate damage to the o-ring.
• 🔗 Gap between sensor and drive disk (must be 0.5–1.5 mm).

2. Check with a multimeter

To test the sensor winding resistance:

1. Disconnect the DPKV connector.
2. Switch the multimeter to resistance measurement mode (200 Ohm).
3. Connect the probes to the sensor contacts (polarity is not important).

Normal values for Octavia A5:

• 🔹 Bosch (original): 550–750 Ohm.
• 🔹 Analogues (Valeo, Hella): 600–900 Ohm.

If resistance 0 ohm (short circuit) or ∞ (break), the sensor must be replaced.

3. Checking with an oscilloscope (for advanced)

This method requires special equipment, but gives 100% results. Connect the oscilloscope to the DPKV signal wire (usually red or yellow) and start the engine. The screen should display stable sine wave with amplitude 0.5–5 V. If the signal is intermittent or absent, the sensor is faulty.

Step-by-step instructions for replacing the crankshaft sensor

Replacing DPKV with Octavia A5 does not require special skills, but there are several critical nuancesthings to consider:

Required tools:

• 🔧 Head or key 10 mm (for fastening bolt).
• 🔧 Flat blade screwdriver (for removing the connector).
• 🔧 Torque wrench (optional for precise tightening).
• 🔧 New sensor (original VAG 06B 906 433 or equivalent).

Work order:

1. Disconnect the battery (remove the negative terminal).
2. Press the latch and disconnect the DPKV connector.
3. Unscrew the fastening bolt (do not lose the washer!).
4. Carefully remove the sensor without damaging the O-ring.
5. Clean the seat from dirt and oil.
6. Install the new sensor, observing original position (see photo above).
7. Tighten the bolt to torque 8–10 Nm.
8. Connect the battery connector and terminal.

After replacement be sure to clear errors through a diagnostic scanner. If the codes appear again, check:

• 🔌 Integrity of the wiring from the sensor to the ECU (often rubbed against the bracket).
• 🛢️ Condition of the drive disc on the crankshaft (may be damaged or contaminated with metal shavings).

⚠️ Attention: On engines 2.0 TDI when replacing DPKV Be sure to check the condition of the crankshaft oil seal. If it leaks, oil can get onto the sensor and damage it again.
