P0616 INFINITI Possible Causes
- Park/neutral position (PNP) relay (starter relay)
- Park/neutral position (PNP) relay (starter relay) harness is open or shorted
- Park/neutral position (PNP) relay (starter relay) circuit poor electrical connection
- Faulty Transmission Control Module (TCM)
How do I fix code P0616 INFINITI?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P0616 INFINITI code

When is the code detected
The P0616 code is detected when the Engine Control Module (ECM) has detected an intermittent short to ground on the starter relay control circuit.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine may not start
P0616 INFINITI Description
Transmission Control Module (TCM) controls park/neutral (PNP) relay (starter relay) in IPDM E/R. TCM switches PNP relay “ON” at “P” or “N” position and allows to crank engine. Then it prohibits cranking other than at “P” or “N” position.
