OBD Code P0510refers to
A closed throttle position switch and wide open throttle position switch are built into the Throttle Position Sensor (TPS) unit. The wide open throttle position switch is used only for A/T control. When the throttle valve is in the closed position, the closed throttle position switch sends a voltage signal to the ECM. The ECM only uses this signal to open or close the EVAP canister purge volume control solenoid valve when the throttle position sensor is malfunctioning.
Symptoms
Possible sumptoms of OBD code P0510
- Engine Light ON (or Service Engine Soon Warning Light) - Engine idle problems - Possible hard to start - Possible shifting problems
Causes
Possible causes of OBD code P0510
- The closed throttle position switch Harness or connectors is shorted - Closed throttle position switch - Throttle position sensor The Error code is generally activated on detection of the following conditions: Malfunction is detected when battery voltage from the closed throttle position switch is sent to ECM with the throttle valve opened.
Possible Solutions
Adjusting the Throttle Position Sensor (TPS) takes care of the problem.
