B0425 Toyota Carina OBD Code

OBD/2 B0425 error code description and symptoms.

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.

At this point we are assuming that the fuses and relays are good. You will need to locate the PCM/TCM and the power input signal circuit using your vehicle information source. Unplug the connector from the PCM/TCM, place the ignition switch in the ON position, and probe the appropriate circuit with the positive test lead of the DVOM.

If your intake air temperature (iat) sensor circuit intermittent low voltage check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system B0425 and engine control unit are in charge of monitoring a bunch of different intake air temperature (iat) sensor circuit intermittent low voltage, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Toyota Carina B0425 OBD2 Code

A common cause of code B0425 is the failure of Intake Air Temperature (IAT) Sensor Circuit Intermittent Low Voltage, but there are several other possible causes as well, such as ;

EVAP canister or fuel tank leaks
Faulty oil control valve (OCV)
Intake Valve Timing Control Solenoid Valve circuit poor electrical connection
Faulty Variable Camshaft Timing (VCT) position solenoid
