The Powertrain Control Module (PCM) sends a Pulse Width Modulated (PWM) signal to DEF Injector to vary the amount of fluid sprayed into the exhaust stream. The PCM will illuminate the MIL lamp after this diagnostic runs and fails. This is a two Trip Fault.
What Are The Potential Causes Of The Jeep P1692 Code?
- DEF injector negative circuit shorted to ground
