P2615 points to a camshaft A (bank 1) position output line that the engine module finds pulled to ground. GM documents it for the Cadillac CT6 in its 2018 tables: with the driver switched off and the line commanded high, the ECM measures the voltage and flags a short at an impedance to ground of 0.5 ohm or less; at 200 kilohm or more it treats the circuit as open, and some controllers then log P2614 instead. It takes 40 failing samples out of 50, read every 100 ms outside cranking and relay voltage is at least 11 V, and GM classes the code Type C without MIL. Mitsubishi lists it for the 2022 Outlander's valve timing module feed. The receiving module may lose cam phase information, so rough starts or a fallback timing strategy are possible.

Likely causes

Output wire chafed through and touching ground
Moisture or corrosion bridging the connector pins to ground
Internally shorted input in the receiving module
Faulty output driver in the engine control module

Symptoms

  • Stored code, often without warning lamp
  • Rough or delayed starting
  • Valve timing control in fallback mode
