Powertrain DTC Charts and Descriptions 4-137
Diagnostic Trouble Code (DTC) Charts and Descriptions
P2315 - Ignition Coil F Primary Control Circuit Low (Continued)
• Damaged ignition coil
• Damaged ignition coil wiring harness
Diagnostic Aids:
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test JF.
P2316 - Ignition Coil F Primary Control Circuit High
Description: This DTC sets when there is a short to voltage in the COP6 circuit.
Possible Causes: • COP6 circuit short to voltage
• Damaged ignition coil
• Damaged ignition coil wiring harness
Diagnostic Aids:
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test JF.
P2418 - EVAP System Switching Valve Control Circuit/Open
Description: This DTC sets when the signal moves outside the minimum or maximum limit for the commanded state of the
evaporative emission (EVAP) vapor blocking valve.
Possible Causes: • VPWR circuit open
• VBV circuit open
• VBV circuit short to ground
• Damaged EVAP vapor blocking valve
Diagnostic Aids:
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HX.
P2450 - EVAP System Switching Valve Performance/Stuck Open
Description: The PCM commands the evaporative emission (EVAP) vapor blocking valve closed while vacuum is present in
the fuel tank. If the valve does not close, the vacuum in the tank is quickly lost. This DTC sets when the rate of vacuum loss is greater than a calibrated threshold.
Possible Causes: • Contaminated EVAP vapor blocking valve
• EVAP vapor blocking valve stuck open
• Damaged EVAP vapor blocking valve
Diagnostic Aids: Retrieve all continuous memory and on-demand self-test DTCs from the PCM. Diagnose and repair any circuit
related EVAP vapor blocking valve DTCs before diagnosing this performance DTC.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HX.
P2510 - ECM / PCM Power Relay Sense Circuit Range/Performance
Description: The ISP-R and the INJPWRM circuits are monitored for correlation. This DTC sets when the voltage on the ISP-
R and the INJPWRM circuit voltages do not correspond for a calibrated period of time.
Possible Causes: • Ignition circuit fuse
• ISP-R circuit open
• ISP-R circuit short to ground
• Fuel injector VPWR circuit short to voltage
• Fuel injector INJPWR circuit short to voltage
• Damaged ignition switch
• Damaged fuel pump relay
• Damaged PCM power relay
