P2615 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Is the car’s Check Engine Light illuminated? Is the car engine stalling and sometimes not starting? Is there a loss of power and acceleration with affected fuel economy? Thus, there might be an issue with the camshaft position sensor or circuit indicating OBD code P2615 error in the ECM/PCM.OBD code P2615 means problem with the Camshaft Position Signal Output Circuit Low Issue.

P2615 is an OBD-II generic code that gets stored in the engine control module (ECM) if it detects the engine camshaft position sensor circuit is not within specifications. If the sensor pulses do not correlate to the pulses of the camshaft sensor, OBD code P2615 will get stored in the system.

What causes this problem with the Camshaft Position Signal Output Circuit Low?

• Camshaft sensor wiring routed too close to spark plug wiring (causing interference)
• Poor wiring connection at camshaft sensor
• Poor wiring connection at PCM
• Bad camshaft sensor
• Damaged reluctor wheel

1. Engine Control Module – It is not always the components, but the ECM that can also be faulty. It can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
2. Powertrain Control Module - Powertrain Control Module can also be faulty in rare cases and thus needs through checks for system and software errors. Thus check and replace it, if required.
3. Electronic Control Unit – The ECU manages the cooling system to control the battery operating temperatures and thus must be replaced if found faulty. Thus, buy new ECU modules and components from us!
4. Diagnostic Tool – Make use of quality diagnostic tools to resolve any OBD error code. Buy quality diagnostic tools from us!
5. Fuel Injector - If there is a leakage in the fuel injectors, then it might cause a rise in the fuel consumption, fuel odours around the vehicle and hard starting. You can always rely on us as we have the best auto parts for our customers.
6. Camshaft Position Sensor – A faulty camshaft position sensor may cause an improper amount of fuel to be injected into the cylinder chamber. The engine may not respond very well to this because it depends on a proper air to fuel ratio to function adequately. Thus, replace faulty sensor now!

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2615 here:

Common Symptoms

• Check Engine Light illumination
• P2615 code getting set in ECM memory
• Engine stalling or not starting
• Engine may have a misfire and may buck or jerk

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2615 code to be stored:

• A technician begins by hooking the vehicle to an OBD-II scanner to verify that the code is present, and check for other codes.
• The freeze frame data along with current data is recorded, and the codes are then cleared to see if they reoccur.
• Visual inspection of the wiring and connectors to check for loose connections, corrosion, or shorts is done.
• A specialized scan tool may be used to test the camshaft sensor. Other tests of the crankshaft and camshaft components may help pinpoint the problem, as well as inspection of the timing chain or timing belt.
• Disconnect and check the resistance and signal voltage from the camshaft sensor.
• Check the sensor reluctor wheel for breakage or damage on the camshaft or camshaft gear.
• If all the components check out, inspect for the fault in the PCM as it can sometimes store wrong OBD code and thus might need replacement or reprogramming.

Common Mistakes When Diagnosing the P2615 Code

Most of the time the camshaft is immediately replaced without analysing the problem as per the OBD code error. Thus proper scan tools need to be used to check for the real cause of the problem that may be ECM, wiring issues, fuel system problems and many more parts other than the camshaft only. Thus proper evaluation and remedy is advisable.
