What Are the Symptoms of P2615?
- Engine cranks but will not start
- Random misfires if engine does run
- Timing-related codes in other modules
- Check engine light on
What Causes P2615? (Most Likely First)
- Short to ground in cam signal output wiring Very High
- ECM cam output driver shorted High
- Receiving module pulling signal low Moderate
- Water intrusion in signal circuit connector Low
Can I Still Drive with P2615?
No — stop driving. P2615 is rated critical severity. Continuing to drive in this state risks further damage — get it looked at before your next trip.
Frequently Asked Questions
Can a module connected to the cam signal cause P2615?
Yes. If another module on the circuit has an internal short, it can pull the signal low. Disconnecting modules one at a time can isolate the faulty one.
Is P2615 always an ECM problem?
Not always. While the output circuit originates at the ECM, wiring shorts and downstream module faults are more common than ECM internal failure.
How does the cam signal affect fuel injection?
The cam signal tells the ECM which cylinder is on its compression stroke, allowing sequential fuel injection. Without it, the ECM cannot fire injectors correctly.
