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

Description:	This DTC sets when the voltage on the ignition switch position run (ISP-R) and the fuel injector power monitor (INJPWRM) circuit voltages do not correspond for a calibrated period of time. 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 Damaged fuel pump relay Damaged PCM power relay
Diagnostic Aids:	The INJPWRM PID voltage should be greater than 10.5 volts when the ignition is in the ON position.
