* Skoda Octavia / Superb / Yeti – selected TDI applications

Aftermarket OE cross-reference data confirms 03L907601 / 03L957147 / 03L957147A as interchangeable OE references for a 3-pin Hall-effect camshaft position sensor used across multiple VAG diesel models. (RIDEX)

CFH Engine Compatibility

Your stated application is a Volkswagen 2.0 TDI CFH-family engine.

This sensor is found on selected engines within the later common-rail diesel family, including CFH-related applications, but the exact engine suffix matters.

Examples may include:

* CFHA

* CFHB

* CFHC

* CFHD

* CFHE

* Other closely related VAG common-rail diesel engines using OE 03L907601 / 03L957147A

Because VAG used several camshaft sensors across different engine revisions, the safest compatibility check is the exact OE number and engine code, rather than simply “2.0 TDI”.

Technical Information

The camshaft position sensor monitors the rotational position of the camshaft.

Its main functions include:

* Detecting camshaft position

* Identifying cylinder timing

* Synchronising camshaft and crankshaft signals

* Supporting accurate fuel injection timing

* Assisting engine start-up

* Providing engine-speed / timing information to the ECU

* Supporting emissions and combustion control

The ECU compares the camshaft signal with the crankshaft position sensor to determine the exact position of the engine during the combustion cycle.

Engine Management System Information

The camshaft position sensor works together with:

* Crankshaft position sensor

* Engine ECU

* Fuel injectors

* High-pressure fuel system

* Camshaft

* Timing belt system

* EGR system

* Turbocharger control

* Engine speed and temperature sensors

Correct camshaft/crankshaft synchronisation is essential for reliable starting and smooth engine operation.

Common Symptoms of a Faulty Camshaft Position Sensor

Replacement may be required if the vehicle develops:

* Difficult starting

* Extended cranking

* Intermittent non-start

* Engine cutting out

* Rough running

* Loss of power

* Limp mode

* Engine management light

* Camshaft position fault codes

* Camshaft / crankshaft correlation faults

* Intermittent ECU synchronisation errors

Common Reasons for Failure

Typical causes include:

* Internal Hall sensor failure

* Wiring damage

* Connector corrosion

* Heat-related deterioration

* Oil contamination

* Damaged sensor cable

* Incorrect sensor gap

* Timing-system problems causing implausible signals

Important Diagnostic Information

Before replacing the sensor, also inspect:

* Electrical connector

* Wiring loom

* Supply voltage

* Earth circuit

* Signal wire

* Crankshaft position sensor

* Timing belt condition

* Mechanical camshaft timing

* ECU fault codes

A camshaft-position fault code does not always mean the sensor itself is defective.

If the timing belt has slipped or mechanical timing is incorrect, the ECU may report a camshaft/crankshaft correlation error even when both sensors are functional.

Diagnostic Testing

A suitable diagnostic tool such as VCDS, ODIS or equivalent can be used to check:

* Camshaft synchronisation

* Engine RPM during cranking

* Camshaft signal plausibility

* Camshaft/crankshaft correlation

* Stored and intermittent fault codes

The sensor is a Hall-effect, 3-pin design according to current OE-equivalent technical data. (RIDEX)

Installation

Typical replacement may involve:

1. Switching off the ignition.

2. Disconnecting the battery where required.

3. Accessing the camshaft sensor.

4. Disconnecting the electrical plug.

5. Removing the retaining bolt.

6. Carefully removing the original sensor.

7. Inspecting the sensor mounting area.

8. Installing the replacement sensor.

9. Reconnecting the electrical connector.

10. Clearing stored fault codes and checking engine operation.

Care should be taken not to damage the sensor wiring or connector during installation.

Programming / Coding

No programming or coding is normally required.

The correct sensor should operate once installed.

However:

* Stored fault codes may need clearing.

* Engine synchronisation values should be checked if the fault remains.

* Mechanical timing should be inspected if correlation faults persist.

Supersession Information

VAG parts data confirms:

03L907601 → 03L957147A

The later part number supersedes the earlier sensor across Volkswagen Group applications. (Oemwolf)

OE-equivalent manufacturers also cross-reference:

* 03L907601

* 03L957147

* 03L957147A

as equivalent sensor references. (RIDEX)

Important Compatibility Note

Before ordering, please compare:

* OE number 03L907601

* Replacement OE number 03L957147A

* Engine code

* Sensor shape

* Cable length

* 3-pin electrical connector

* Mounting-hole position

* Your original sensor against the listing photographs

* Vehicle VIN where possible

Do not rely only on “2.0 TDI CFH”, because CFH-family engines include several different suffixes and production revisions.

The safest compatibility wording is:

Volkswagen / Audi / SEAT / Skoda selected 1.6 & 2.0 TDI applications using OE 03L907601 / 03L957147A.

Condition

Genuine used Volkswagen Group part.

As a used engine-management sensor, it may show normal signs of previous use including:

* Surface marks

* Oil or engine residue

* Light oxidation around mounting areas

* General age-related cosmetic wear

Please inspect all listing photographs carefully for the exact condition, connector, cable and mounting point.
