When the engine is being cranked, battery voltage is applied to the powertrain control module (PCM). On a cold engine the PCM can increase the fuel injection volume and modify ignition timing when receiving the start signal. This signal passes through the park neutral position (PNP) switch or the clutch pedal position (CPP) switch. If this signal is not detected during engine cranking, the PCM will still allow the engine to start.
• | The battery voltage is greater than 10.5 volts. |
• | Engine speed is greater than 1,000 RPM. |
• | Vehicle speed is greater than 20 km/h (12 mph). |
• | DTC P0617 runs continuously once the above conditions have been met. |
A high voltage is input on the Crank Signal circuit of the PCM for greater than 20 seconds after starting the engine.
DTC P0617 is a type A DTC.
DTC P0617 is a type A DTC.

⇒ | If the test lamp illuminates, test the crank signal circuit for a short to voltage. If the circuit tests normal, test for a faulty PNP switch with AT or a faulty clutch pedal position switch with MT. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
