- A Throttle Position Sensor with a poor electrical connection.
- Or a Faulty Engine Control Module (ECM).
Fixing Error Code p0220 Step By Step
Address the throttle position sensor circuit issue associated with fault code P0220.
- To fix OBDII code P0220, first, review the possible causes related to the Throttle/Pedal Position Sensor/Switch B circuit.
- Visually inspect the wiring harness and connectors for any damage.
- Check the connector pins for signs of being broken, bent, pushed out, or corroded.
- Test the Throttle/Pedal Position Sensor/Switch B for proper operation.
- Replace the sensor if necessary.
- Clear the fault codes and perform a road test to verify the repair.
Cost Of Fixing p0220 Fault Code
Diagnosing and repairing fault code P0220 typically involves testing and replacing the throttle position sensor.
The cost to diagnose and fix OBD code P0220 typically ranges from $75 to $150, with an estimated repair time of 1. 0 hour.
Costs depend on labor rates, shop fees, and the complexity of the throttle position sensor circuit issue.
Details of the p0220 OBD Code
P0220 code relates to an issue with the throttle position sensor circuit.
OBD code P0220 indicates an issue with the Throttle/Pedal Position Sensor/Switch B Circuit.
This code is triggered when the Engine Control Module (ECM) detects a discrepancy in the signals from the throttle position sensor or pedal position sensor B.
The ECM uses these signals to determine the desired throttle position and adjust engine performance accordingly.
If there is a fault in this circuit, it can lead to drivability issues and poor engine performance.
Mechanic’s Tech Notes
Diagnostic notes for fault code P0220: Throttle/Pedal Position Sensor/Switch B Circuit Malfunction.
To diagnose and fix OBDII code P0220, you should first check the throttle position sensor (TPS) circuit for any issues.
Use a voltmeter to test the TPS sensor’s voltage signal while manually moving the throttle.
Ensure the voltage changes smoothly without any sudden drops or spikes.
If the voltage readings are erratic, the TPS may need replacement.
Additionally, inspect the TPS wiring harness and connector for any damage or corrosion.
Clean or repair any faulty connections.
Reset the fault code using a scan tool after making any repairs to see if the issue is resolved.
