P0692 on Jeep
Fan 1 Control Circuit High
P0692 on Jeep vehicles indicates fan 1 control circuit high. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. This code means the engine computer detected high voltage (or an open circuit) in the control circuit for cooling fan 1. The PCM commands the fan through a relay and watches the circuit voltage; a high reading usually indicates an open or a relay/wiring fault. If the fan fails to run, the engine can overheat at idle or in slow traffic. Typical repair costs on Jeep range from $450 to $1,600, depending on the specific model and root cause.
Common Causes of P0692
- •Faulty cooling fan relay
- •Open circuit in the fan control wiring
- •Failed cooling fan motor
- •Corroded or disconnected fan connector
- •Blown fuse feeding the fan circuit
- •PCM control driver fault

Jeep Grand Wagoneer(1 issue)
- Cooling Fan Module Failure / Overheating Warning2021-2023
The electric cooling fan module on the Grand Wagoneer has been documented to fail, causing the dual electric radiator fans to run at reduced speed or stop entirely, resulting in engine coolant temperature spikes especially at low speeds and in traffic. The fan control module can develop internal MOSFET failures due to heat cycling, and Stellantis issued related service guidance through their dealer network. Owners report the temperature gauge rising into the red zone during stop-and-go driving and the A/C compressor cutting out as a secondary symptom.

What does P0692 mean on Jeep?▼
P0692 stands for "Fan 1 Control Circuit High." This code means the engine computer detected high voltage (or an open circuit) in the control circuit for cooling fan 1. The PCM commands the fan through a relay and watches the circuit voltage; a high reading usually indicates an open or a relay/wiring fault. If the fan fails to run, the engine can overheat at idle or in slow traffic. On Jeep specifically, this code is documented across 1 model.
