P0123 1998 FORD F150 Code - Throttle Position Circuit High Input
|P0123 1998 FORD F150 code possible causes
- Faulty throttle position sensor
- Throttle position sensor harness is open or shorted
- Throttle position sensor circuit poor electrical connection
|How do I fix the P0123 1998 FORD F150 code?Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
|P0123 1998 FORD F150 code tech notesThe TP sensor circuit is monitored by the PCM for a high TP rotation angle (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine OFF or key ON engine running the TP rotation angle (or voltage) changes above maximum calibrated limit, the test fails.
A TP PID (TP V PID) reading greater than 93% (4.65 volts) in key ON engine OFF, continuous memory or key ON engine running indicates a hard fault.
|Cost of diagnosing the P0123 1998 FORD F150 code
Labor: 1.0The cost of diagnosing the P0123 1998 FORD F150 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
|When is the P0123 1998 FORD F150 code detected?The Throttle Position Sensor (TPS) signal 1 circuit has reported a high voltage
|What are P0123 1998 FORD F150 code possible symptoms?
- Engine Light ON (or Service Engine Soon Warning Light)
|P0123 1998 FORD F150 code descriptionThe Throttle Position Sensor (TPS) responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (ECM). In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM.
Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.
