Camshaft A Position Signal Output Circuit Low Bank 1
What it means
P2615 means the camshaft position signal output on bank 1 is reading low — the voltage on that circuit is below the expected range. The engine relies on the cam signal to time injection and spark, so a weak or dropping signal can cause hard starting, stalling, and rough running, and occasionally prevents the engine from starting. The cause is usually a wiring fault or a failing camshaft sensor rather than mechanical timing.
Can I keep driving? Drive cautiously — a low camshaft-signal output can cause hard starting, stalling, and occasionally a no-start, so get it checked soon.
Common symptoms
What you'll notice
- Check-engine light on
- Hard starting or extended cranking
- Stalling or intermittent no-start
- Rough running, hesitation, or misfire feel
Common causes
Most likely first
- Short-to-ground or high resistance in the camshaft signal output wiringLikely
- Faulty camshaft position sensor on bank 1Common
- Corroded or loose sensor connector, or a poor groundCommon
- Damaged reluctor/tone ring or excessive air gapLess often
- Faulty PCMLess often
How to diagnose & fix
Work through it in order
- Scan and confirm the code, then read live camshaft-signal data while cranking.
- Inspect the bank 1 cam sensor connector and wiring for a short-to-ground or chafing.
- Check the sensor's power, ground, and signal circuits with a meter.
- Inspect the sensor and its tone ring for damage or the wrong air gap.
- Replace the sensor if it fails testing; consider the PCM only after wiring is verified good.
