Owners ŠKODA Octavia TUR with turbocharged engines 1.4 TSI, 1.8 TSI or 2.0 TSI sooner or later they face the need to check or replace the oil pressure sensor. This small but critical element is responsible for controlling the engine's lubrication system. If it fails, the dashboard lights up oil lamp icon, and the on-board computer may give an error P0520 or P0523.

The problem is that the location of the oil pressure sensor is on Octavia TUR depends on the generation of the car, engine type and even year of manufacture. In this article we will look at exact installation locations for all modifications, we will show photos and diagrams, and also explain how to diagnose the malfunction yourself. No unnecessary theory - only specific instructions and verified data.

1. Which oil pressure sensor is installed on the ŠKODA Octavia TUR?

On Octavia TUR (including restyled versions) two types of sensors are installed:

  • 🔹 Mechanical oil pressure sensor — transmits an analog signal to the dial indicator on the dashboard (if there is one). Used on models up to 2013.
  • 🔹 Electronic emergency oil pressure sensor — works on the “yes/no” principle and is triggered only when the pressure drops critically (lights the lamp 🛢️ on the panel). Installed on all versions, including new ones.

On most Octavia TUR with motors 1.4 TSI (CZDA, CZEA), 1.8 TSI (CZPA, CZPB) and 2.0 TSI (CZPB, CZPC) worth it combined sensor, which combines both functions. Its catalog numbers:

EngineOriginal numberAnalogs (brand)
1.4 TSI (CZDA)03C919081ABosch 0 261 231 046, Hella 6PU 008 137-001
1.8 TSI / 2.0 TSI (CZPA, CZPB)06H919081Valeo 583033, Febi 26127
2.0 TSI (CZPC, after 2017)06K919081BBeru DS450, VDO A2C59502919

Important! On restyled Octavia FL (2017+) with motor 2.0 TSI (CZPC) the sensor may have a different connector. Please check visually or by VIN before purchasing.

2. Where is the oil pressure sensor located: diagrams and photos

The location of the sensor depends on engine type and year of manufacture. Below are the exact coordinates for each modification.

2.1. Engines 1.4 TSI (CZDA, CZEA, ACT)

On Octavia TUR with motor 1.4 TSI The oil pressure sensor is located:

  • 📍 At the back of the engine, next to the oil filter (from the gearbox side).
  • 🔧 Access possible only from below — it is necessary to remove the crankcase protection or use an inspection hole.
  • 🔌 The connector is directed upwards, it fits the sensor one wire (black or grey).
Photo of the location on the 1.4 TSI

The photo shows that the sensor is screwed into the cylinder block to the right of the oil filter. It has a 24 mm hex head and a plastic connector with a lock.

2.2. Engines 1.8 TSI and 2.0 TSI (CZPA, CZPB, CZPC)

On more powerful engines 1.8 TSI and 2.0 TSI The oil pressure sensor is installed differently:

  • 📍 Top, on the cylinder block, next to the turbine (from the intake manifold side).
  • 🔧 Access possible from above, but it is necessary to remove the decorative engine cover and the air duct pipe.
  • 🔌 The connector may be two-pin (on new models) or single-contact (on old ones).

On 2.0 TSI (CZPC) after 2017, the sensor is often hidden under the thermostat. To get to it, you will have to unscrew the bracket securing the pipes.

3. Signs of a malfunctioning oil pressure sensor

If the oil pressure sensor is on Octavia TUR starts to “lie” or fails, this manifests itself as follows:

  • ⚠️ Oil pressure light is on (🛢️) at idle, but goes out as the speed increases.
  • ⚠️ False errors in the on-board computer: P0520 (sensor circuit malfunction), P0523 (high beep).
  • ⚠️ Pressure indicator (if any) shows zero values or “freezes” in one position.
  • ⚠️ The engine goes into emergency mode for no apparent reason (especially on 2.0 TSI).

Important! If the oil pressure light is on constantly (regardless of the speed), the problem may not be in the sensor, but in oil pump, clogged filter or low oil level. First check the level with a dipstick!

💡

Before replacing the sensor, clear errors via a diagnostic scanner (for example, VCDS or OBDeleven). If the error appears again, the sensor is definitely faulty.

4. How to check the oil pressure sensor on an Octavia TUR

There are three reliable diagnostic methods:

4.1. Checking with a multimeter (for electronic sensor)

  1. Remove the connector from the sensor.
  2. Connect multimeter in ohmmeter mode to the sensor contacts.
  3. When the ignition is turned off, the resistance should be infinity (open circuit).
  4. When the engine is running (at idle), the resistance should drop to 0 ohm (the circuit is closed).

4.2. Checking with a mechanical pressure gauge

The most accurate method is to connect external pressure gauge instead of a sensor:

  1. Unscrew the oil pressure sensor.
  2. Connect via adapter mechanical pressure gauge (for example, Stahlwille 710/1).
  3. Start the engine. At idle speed the pressure should be not less than 0.5 bar, at 3000 rpm - 2.0–4.5 bar.

If the pressure is normal and the lamp is on, the sensor is faulty. If the pressure is low, there is a problem in the lubrication system.

4.3. Diagnostics via VCDS (VAG-COM)

Using a diagnostic scanner (VCDS, OBDeleven) you can check the sensor parameters in real time:

  1. Connect to the block 01 - Engine.
  2. Go to Measuring Blocks.
  3. Find the parameter Oil Pressure or G266.
  4. Compare the readings with the norm (see table below).
Operating modeNormal pressure (bar)Critical value
Idling (800 rpm)0.5–1.0< 0.3
2000 rpm1.5–2.5< 1.0
4000 rpm3.0–4.5< 2.0
💡

If the oil pressure is normal, but the light is on, there is a 90% chance that the sensor is to blame. If the pressure is low, look for the cause in the oil pump, filter or sump.

5. Step-by-step instructions for replacing the sensor

Replacing the oil pressure sensor with Octavia TUR takes 20–40 minutes depending on access. You will need:

  • 🔧 24 mm wrench (or socket with extension).
  • 🔧 Torque wrench (optional for precise tightening).
  • 🧴 New O-ring (included with the sensor).
  • 🧤 Gloves and rags (oil may leak!).

5.1. Replacement with 1.4 TSI (access from below)

  1. Raise the car on a lift or drive it into a viewing hole.
  2. Remove the crankcase protection (unscrew the 4 bolts around the perimeter).
  3. Locate the sensor near the oil filter. Disconnect the connector by pressing the latch.
  4. Using a 24mm wrench, unscrew the sensor. Be prepared for oil to spill!
  5. Install a new sensor with a new gasket. Tighten firmly 20–25 Nm.

5.2. Replacement with 1.8 TSI / 2.0 TSI (access from above)

  1. Remove the decorative engine cover.
  2. Disconnect the air duct pipe from the turbine (loosen the clamps).
  3. Locate the sensor on the cylinder block (see photo in section 2.2).
  4. Disconnect the connector and unscrew the sensor. If necessary, remove the pipe bracket.
  5. Install a new sensor, connect the connector. Check for leaks.

Warning: On 2.0 TSI (CZPC) after 2017, the sensor can be “hidden” under the thermostat. If you don’t see it right away, remove the thermostat (3 10 mm bolts).

💡

After replacing the sensor, reset the errors using the diagnostic scanner. If the oil pressure light remains on, check the wiring from the sensor to the ECU.

6. Common mistakes when replacing and how to avoid them

Even experienced car owners sometimes make mistakes that lead to repeated problems. Here are the most common:

  • ❌ Using an old O-ring - leads to oil leakage. Always install the new ring included in the kit.
  • ❌ Dragging the sensor - may damage the threads in the cylinder block. Maximum force: 25 Nm.
  • ❌ Ignoring dirt around the sensor — debris getting into the oil channels can lead to clogging. Clean the area before replacing!
  • ❌ Buying a non-original sensor - cheap analogues often lie. Take only proven brands (Bosch, Hella, VDO).
⚠️ Attention! On Octavia TUR with motor 2.0 TSI (CZPC) after 2017 the oil pressure sensor may have another connector (mini-Fit Jr.). Before purchasing, check the catalog using the VIN code!

7. How much does it cost to replace the oil pressure sensor?

The cost of work and spare parts depends on the region and type of service. Below are the estimated prices for Russia and the CIS (for 2026):

ItemCost (rubles)Cost (₴, Kazakhstan)

Analogue (Bosch/Hella)1 200–2 5008 000–16 000
Replacement in service800–1 5005 000–10 000
Diagnostics (VCDS)500–1 0003 000–6 000

If you decide to replace the sensor yourself, the total cost will be 1 200–2 500 ₽ (spare part only). In service with work - 2 500–5 000 ₽.

Tip: Buy the sensor only from trusted stores (for example, Exist.ru, Autodoc) and check availability warranty card. Counterfeits often fail after 1–2 months.

FAQ: Frequently asked questions about the oil pressure sensor on the Octavia TUR

🔧 Is it possible to drive if the oil pressure light is on?

No! If the lamp is on constantly, this means that the oil pressure is critically low. Further driving will lead to scuff on the crankshaft and engine jam. Immediately stop the engine and check the oil level.

If the lamp flashes or lights up at idle, you can drive to the service center, but no more than 50–100 km at low speeds (up to 2500 rpm).

🛠️ Which oil pressure sensor is suitable for Octavia A7 (2013–2020)?

For Octavia A7 (including facelift) with engines 1.4 TSI (CZDA) and 1.8/2.0 TSI (CZPA, CZPB) original sensor fits 06H919081 or its analogues:

  • Bosch 0 261 231 046
  • Hella 6PU 008 137-001
  • Febi 26127

For 2.0 TSI (CZPC, after 2017) need a sensor 06K919081B.

🔍 How to reset P0523 after replacing the sensor?

Error P0523 (high oil pressure sensor signal) is reset via the diagnostic scanner:

  1. Connect VCDS or OBDeleven.
  2. Go to block 01 - Engine.
  3. Select Clear fault codes.
  4. Start the engine and check if the error appears again.

If an error is returned, check wiring integrity or replace the sensor with another one (possibly defective).

🚗 Can the oil pressure sensor affect fuel consumption?

No, oil pressure sensor does not affect directly on fuel consumption. However, if due to a faulty sensor the ECU puts the engine into emergency mode, this can increase consumption by 10–15%.

The sensor is indirectly connected to the lubrication system: if the actual oil pressure is low (and the sensor does not detect this), the engine operates with increased friction, which also leads to excessive fuel consumption.

🔄 How often should the oil pressure sensor be replaced?

The oil pressure sensor is not a consumable, and there is no need to change it “according to the regulations”. It lasts as long as the engine if:

  • Not subject to mechanical damage.
  • Do not fill with fake or low-quality oil.
  • The engine does not overheat.

Replacement is only required when obvious signs of malfunction (see section 3). Average service life of the original sensor - 150–200 thousand km.
