B0425 Belsize 12 OBD Code

OBD/2 B0425 error code description and symptoms.

The Throttle Position sensor signals the Engine Control Module as to the current position of the engine throttle valve.
The current throttle valve opening is based on the driver's input from the gas pedal. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

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.

B0425 Belsize 12 Error Code Repair Process :

If your vehicle failed a B0425 test and the B0425 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses intake air temperature (iat) sensor circuit intermittent low voltage a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look intake air temperature (iat) sensor circuit intermittent low voltage: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Belsize 12 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 ;

Damaged ECM
Faulty starter motor
Faulty Variable Camshaft Timing (VCT) position solenoid
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
