P2616
Camshaft A Position Signal Output Circuit High Bank 1
Camshaft position signal output
Generic OBD-II
Low
What it means
P2616 means the control module sees an abnormally high voltage on the camshaft position signal output circuit for bank 1 — the buffered cam signal it sends out to other modules or accessories. It usually points to a wiring short-to-voltage or a module fault rather than a problem that stops the engine from starting.
Low
Can I keep driving? Usually drivable. The engine still runs, but modules that rely on the cam signal output may behave oddly, so get it checked.
Common symptoms
What you'll notice
- Check-engine light on
- Possible tachometer or accessory-module irregularities
- Often no obvious driving symptom
- Occasional related timing or sensor codes stored alongside it
Common causes
Most likely first
- Short to voltage in the camshaft position signal output circuitLikely
- Damaged, chafed, or corroded wiring or connector on the output circuitCommon
- Poor ground affecting the buffered cam signalCommon
- Internal fault in the control module driving the output signalLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and note any companion camshaft or crankshaft signal codes.
- Inspect the cam signal output wiring and connector for shorts to power, chafing, or corrosion.
- Check the circuit for a short to voltage and verify a clean ground.
- If wiring checks out, have the control module's signal output tested and replace only if confirmed faulty.
FAQ
Quick answers
Is it safe to drive with P2616?+
Usually yes for short trips. This is the cam signal the module sends out to other devices, so the engine typically still runs, but have it diagnosed before relying on it.
Can I just clear P2616?+
It will return until the short-to-voltage or wiring fault on the output circuit is repaired.
