Code Definition

P1282 — Fuel pump relay control circuit

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Chrysler

About P1282

P1282 is a manufacturer-specific powertrain diagnostic trouble code recorded for Chrysler vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1282 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1282 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

On Chrysler vehicles, P1282 sets when the PCM detects an electrical fault in the fuel pump relay control circuit. The PCM switches the control side of the fuel pump relay to energise the fuel pump, and it monitors that circuit to confirm the relay responds correctly. The code is logged when the PCM sees an open circuit, a short to ground, a short to voltage, or no expected change when it commands the relay on or off. Because this circuit controls power to the fuel pump, a fault can cause a no start, intermittent stalling, or cranking with no fuel pressure, and the check engine light will be on...
