P0510

DTC P0510, sometimes indicated as P051000 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the engine idling stability causing closed throttle position switch malfunction.

The closed throttle position switch is a sensor that monitors the position of the throttle valve. If this switch malfunctions, it can cause the engine to stall or the Check Engine Light to come on.
There are several possible causes of a closed throttle position switch malfunction, including a bad switch, a wiring problem, or a problem with the throttle valve itself.
The best way to diagnose a closed throttle position switch malfunction is to check the sensor's output voltage with a scan tool. If the voltage is outside of the normal range, there is likely a problem with the sensor.
If the sensor is found to be bad, it can be replaced. If there is a wiring problem, the wiring should be checked and repaired as necessary. If there is a problem with the throttle valve, it may need to be replaced.
