DTC P0690: ELECTRONIC CONTROL MODULE (ECM)/POWERTRAIN CONTROL MODULE (PCM) POWER RELAY SENSE CIRCUIT HIGH

Description:  The powertrain control module (PCM) monitors the voltage on the ignition switch position run (ISP-R) and the fuel injector power monitor (INJPWRM) circuits. 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: 
  • ISP-R circuit short to voltage in the harness
  • Fuel injector voltage power (VPWR) circuit open
  • Fuel injector power monitor (INJPWR) circuit open
  • Damaged ignition switch
