P012B code typically indicates an issue with the intake air temperature sensor circuit.
- P012B can be caused by a faulty Turbocharger/Supercharger Inlet Pressure Sensor.
- A Turbocharger/Supercharger Inlet Pressure Sensor harness that is open or shorted.
- A Turbocharger/Supercharger Inlet Pressure Sensor circuit with a poor electrical connection.
Fixing Error Code p012b Step By Step
To address fault code P012B, inspect and potentially replace the intake air temperature sensor.
- To fix OBDII code P012B, first, review the ‘Possible Causes’ mentioned above and visually examine the corresponding wiring harness and connectors.
- Ensure to check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.
- Next, check the throttle position sensor (TPS) for proper operation and wiring integrity.
- Test the TPS using a multimeter to verify its resistance values.
- If the TPS is faulty, replace it with a new one.
- Clear the fault code using an OBDII scanner and test drive the vehicle to ensure the code does not return.
Cost Of Fixing p012b Fault Code
Diagnosing and repairing fault code P012B may involve inspecting and replacing the fuel pressure regulator.
The cost to diagnose and fix OBD code P012B typically ranges from $75 to $150, with an estimated repair time of 1. 0 hour.
The total cost depends on labor rates, shop fees, and the complexity of the repair.
Details of the p012b OBD Code
Fault code P012B relates to the intake air temperature sensor showing a low input signal.
OBD code P012B means Turbocharger/Supercharger Inlet Pressure Sensor Circuit Range/Performance.
This code is triggered by the Engine Control Module (ECM) when it detects that the signal from the turbocharger/supercharger inlet pressure sensor is outside the expected range or performance parameters.
The sensor is responsible for monitoring the pressure of the air entering the turbocharger or supercharger, providing crucial data for engine performance and efficiency.
Mechanic’s Tech Notes
Code P012B indicates a problem with the intake air temperature sensor circuit range/performance.
OBDII code P012B relates to the intake air temperature sensor 2 circuit range/performance issue.
To diagnose, use a voltmeter to test the sensor’s resistance and voltage output.
Check the wiring harness and connectors for any damage, corrosion, or loose connections.
Ensure the sensor is receiving proper voltage and ground.
Use a scan tool to monitor live data and confirm sensor readings.
If all checks out, consider replacing the intake air temperature sensor.
Reflashing the engine control module may also be necessary to clear the fault code.
FAQ
