What sensor does the PCM use to determine the appropriate throttle angle?
What sensor does the PCM use to determine the appropriate throttle angle?
throttle position sensor
The throttle position sensor (TPS) is usually connected to the throttle plate shaft in the throttle body. The TPS reads the angle of the throttle valve and transmits an electrical signal to the PCM. The PCM uses this real time signal to help calculate or modify fuel injector pulse width, controlling air/fuel mixture.
How to test the throttle position sensor ( 4.2L Ford F150 )?
P0121: Throttle Position (TP) Circuit Performance Problem. P0122: Throttle Position (TP) Circuit Low Input. P0123: Throttle Position (TP) Circuit High Input. Your 4.2L Ford pick up (van) fails the smog check (state mandated emissions test).
Can a 4.2L Ford TP sensor be defective?
This confirms that your 4.2L Ford’s TP sensor is OK and not defective. CASE 2: The throttle angle voltage DID NOT increase/decrease as you opened/closed the throttle plate. This tells you that the TPS is bad and causing the TPS trouble code lighting up the check engine light (CEL) on your 4.2L Ford.
Where does the throttle position sensor come from?
The PCM (Powertrain Control Module=Fuel Injection Computer) feeds the throttle position sensor with 5 Volts and a Ground. This Ground is known as the Sensor Return in Ford tech speak.
How does the TP sensor work on a Ford Focus?
This Ground is known as the Sensor Return in Ford tech speak. As you step on the accelerator pedal, the TP sensor translates the amount of throttle plate opening (caused by the accelerator cable) into a voltage signal the PCM can use.
How to reset the throttle position sensor on a Ford F150?
I’m told there is a sequence of turning the key on and off and pressing the gas pedal down to open up the throttle position sensor on the 2004-2008 model 5.4L’s?
Where is the main ground located in the PCM for Ford F150?
1 Made sure PCM had power and ground, 2. Checked voltage on TPS, Coolant sensor, 3. Traced all grounds I could fins to make sure had proper/good connections. When I jump ground to body from signal wire everything works – transmission malfunction indicator light goes off, coolant temp light goes off and coolant gage starts working. 4.
