P235B Toyota Platz OBD Code

OBD/2 P235B 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.

As long as the throttle plate remains closed, the idling speed and quality is controlled by the PCM via the idle control valve, and as can be seen from the above it should be clear that idle control on a gasoline engine is a complex affair. For instance, if the engine is started in sub-zero temperatures, the PCM will command the idling control valve to allow less air to enter the engine to enrich the air/fuel mixture to create a condition which is roughly analogous to how chokes worked on carburetted engines to control idling in cold weather.

Common Causes of Toyota Platz P235B OBD2 Code

A common cause of code P235B is the failure of Output Circuit Check Signal Low, but there are several other possible causes as well, such as ;

EVAP canister or fuel tank leaks
1Camshaft Position Sensor circuit poor electrical connection
Faulty Variable Camshaft Timing (VCT) position solenoid
Incorrect Positive Crankcase Ventilation (PCV) hose connection
