Low Speed Fuel Pump Primary Circuit Malfunction The PCM monitors the low speed fuel pump (LFP) primary circuit output from the PCM.
The test fails if: When the LFP circuit is commanded on (grounded), excessive current draw is detected on the LFP circuit; or when the LFP circuit is commanded off, voltage is not detected on the LFP circuit (the PCM expects to detect VPWR voltage coming through the low speed fuel pump relay coil to the LFP circuit). Open or shorted low fuel pump (LFP) circuit Open VPWR to low speed fuel pump relay Damaged low speed fuel pump relay Damaged PCM An open circuit or short to ground can only be detected with the low speed fuel pump.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U1286, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U1286 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

EVAP canister or fuel tank leaks
Damaged camshaft position (CMP) sensor
Intake air leaks
Internal electrical failures in actuator motors/solenoids.
