What it means
The camshaft position signal output circuit voltage is below the expected level. This code does not specify a camshaft A sensor or bank.
At a glance
- Usually lights the check-engine light
How it works
The camshaft position signal output circuit sends a timing signal from the engine controller to a connected system or module. P2615 sets when the output voltage is below the expected level, often from a short to ground or a faulty output driver; this code does not name a particular camshaft, bank, or sensor.
Common causes
Most likely first.
- Output wire shorted to ground
- Output buffer transistor failed
- Connector pins corroded - high contact resistance
Symptoms
- Check-engine light
- Engine may crank longer, run poorly, or fail to start
How to diagnose it
- Record freeze-frame data and related timing codes, and note any extended cranking or rough running.
- Inspect the camshaft signal output wiring and connectors for chafing against ground, corrosion, loose terminals, or a pushed-back pin.
- With the circuit isolated as specified in service information, check the output wire for a short to ground.
- Check connector pin contact and continuity through the output circuit to locate excessive resistance or a damaged section.
- If the wiring checks out, verify the controller's signal output under the manufacturer's procedure.
Common fixes
- Repair chafed output-wire insulation that is grounding the circuit.
- Clean and secure corroded or loose connector terminals.
- Repair damaged output-circuit wiring.
- Repair or replace the controller only if its output driver is confirmed faulty.
Can I keep driving?
If the engine runs normally, limited driving may be possible, but poor running or a no-start can develop. Avoid long or high-risk trips until the signal circuit is checked.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
