- Inspect the fuel pump relay control circuit for any open or short to ground condition
- Inspect the fuel pump relay power circuit for any open condition
- Replace the fuel pump relay as necessary
- Replace the PCM as necessary
When you experience Jeep Code P1282, it can be a difficult issue to diagnose and fix. Jeep Code P1282 is defined as a Fuel Pump Relay Control Circuit Malfunction. When the key is turned on or the engine is started, the system voltage is over 10.5v, and the PCM detected an unexpected voltage condition on the Fuel Pump Relay control circuit during the CCM test period. There are a few causes and solutions for this issue that can help you get your Jeep back on the road. With knowledge of what is causing the Jeep Code P1282, you can take the necessary steps to repair the issue.
Causes and Solutions for Jeep Code P1282
| Cause | Solution |
|---|---|
| Fuel pump relay control circuit is open or shorted to ground | Inspect the fuel pump relay control circuit for any open or short to ground condition |
| Fuel pump relay power circuit is open (test power from Ignition) | Inspect the fuel pump relay power circuit for any open condition |
| Fuel pump relay is damaged or has failed | Replace the fuel pump relay as necessary |
| PCM has failed | Replace the PCM as necessary |
Inspect the Fuel Pump Relay Control Circuit
When diagnosing Jeep Code P1282, the first step is to inspect the fuel pump relay control circuit. This circuit is responsible for powering the fuel pump relay, which is what allows for the fuel pump to be turned on. If the circuit is open or shorted to ground, the fuel pump will not be able to turn on. To inspect the circuit, you should check the wiring and connectors for any signs of damage or corrosion. If any damage is found, it should be repaired or replaced as necessary.
Inspect the Fuel Pump Relay Power Circuit
The next step when diagnosing Jeep Code P1282 is to inspect the fuel pump relay power circuit. This circuit is responsible for supplying power to the fuel pump relay from the ignition switch. If this circuit is open, the fuel pump will not be able to turn on. To inspect the circuit, you should check the wiring and connectors for any signs of damage or corrosion. If any damage is found, it should be repaired or replaced as necessary.
Replace the Fuel Pump Relay
If the fuel pump relay is damaged or has failed, it should be replaced as necessary. The fuel pump relay is responsible for powering the fuel pump, which is what allows for the fuel pump to be turned on. If the relay is not functioning correctly, the fuel pump will not be able to turn on, resulting in Jeep Code P1282.
Replace the PCM
If the PCM has failed, it should be replaced as necessary. The PCM is responsible for controlling the fuel pump relay. If the PCM is not functioning correctly, the fuel pump relay will not be able to turn on, resulting in Jeep Code P1282.
Conclusion
Jeep Code P1282 is a Fuel Pump Relay Control Circuit Malfunction that can be caused by a variety of issues. By inspecting both the fuel pump relay control circuit and the fuel pump relay power circuit, as well as replacing the fuel pump relay and PCM as necessary, it is possible to diagnose and fix the issue. With the correct diagnosis and repair, you should be able to get your Jeep Code P1282 issue resolved and get back on the road.
