P2615Camshaft Position Signal Output Circuit Low

Q: What does code P2615 mean?

Camshaft Position Signal Output Circuit Low. P2615 means the engine control module (ECM) has detected that the camshaft position signal output circuit is reporting a voltage lower than expected for the current operating conditions. The ECM monitors this circuit to determine camshaft position and uses that data for fuel injection and variable valve timing; a low signal can disrupt those functions.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Rough idle or misfire, especially when the engine is cold
Reduced engine performance or lack of power during acceleration
Poor fuel economy due to incorrect injection timing
Intermittent stalling or difficulty starting
In some cases, the engine may enter limp mode

Common causes, most likely first

Faulty camshaft position sensor or its internal circuitry
Damaged or corroded wiring in the camshaft position signal output circuit
Loose or corroded electrical connector at the sensor or ECM
Failed ECM driver for the signal output circuit
Aftermarket or incorrect sensor installed previously
Oil or debris contamination on the sensor or reluctor wheel
Mechanical timing issues such as a stretched timing chain or worn camshaft phaser

How to diagnose and fix it

Use a scan tool to verify P2615 is current and check for related camshaft or crankshaft codes
Inspect the camshaft position sensor connector and wiring for damage, corrosion, or loose pins
Measure the signal output voltage at the sensor with a multimeter and compare to specifications
Check the sensor's ground and power supply circuits for continuity and voltage drops
Perform a wiggle test on the harness while monitoring live data to detect intermittent faults
Replace the camshaft position sensor if tests indicate it is faulty
If the sensor and wiring are good, diagnose the ECM driver circuit or replace the ECM as needed

Common misdiagnosis traps for P2615

A low signal output can be caused by a poor ground connection at the sensor or ECM, which is often overlooked when replacing the sensor.
Aftermarket sensors with incorrect resistance values can set this code even when new, so always use OEM-quality parts.
The code can be triggered by a mechanical issue like a worn camshaft phaser or timing chain, not just an electrical fault.
Intermittent wiring faults may only appear when the engine is hot or vibrating, so a wiggle test is essential.
Some vehicles use a shared ground for multiple sensors, so a fault in another circuit can affect the camshaft signal.

Can I keep driving with P2615?

You can usually drive the vehicle with this code, but avoid heavy acceleration or towing until it is repaired. If the engine runs rough or stalls, seek service immediately to prevent damage to the catalytic converter or other components.
