Operation



Specific to:

Chrysler Sebring 2008-2009

Dodge Avenger 2008-2009

The Powertrain Control Module (PCM) receives a throttle position signal by providing the Throttle Position Sensor (TPS) with a 5-volt pull up circuit, a sensor ground circuit, and a signal circuit. The signal is checked for being out of range as well as for intermittent operation (excessive signal changes).

Testing



Specific to:

Chrysler Sebring 2008-2009

Dodge Avenger 2008-2009


NOTE
Refer to the Electrical Wiring Diagram for component and connector locations, connector views, and circuit-specific information.

Connection & Wiring Diagnosis

Specific to:

Chrysler Sebring 2008-2009

Dodge Avenger 2008-2009

Refer to the Electrical Wiring Diagram for component and connector locations, connector views, and circuit-specific information.  

Many intermittent open or short circuits may be caused by wiring harness and connector movement due to vibration, engine torque, bumps and rough pavement, etc.

  1. Test the wiring harness and connectors by performing the following tests:

    Move the related connectors and wiring while monitoring the appropriate scan tool data.  
     
    Move the related connectors and wiring with the component commanded ON and OFF. Using a suitable the scan tool, observe the component operation.
     
    With the engine running, move the related connectors and wiring while monitoring component operation.
     
    If harness or connector movement affects the data displayed, the component and system operation, or the engine operation, inspect and repair the harness or connections as necessary.
     

  2.  
  3. Test the connector terminal pins and/or wiring by performing the following tests:

    Inspect for incorrect mating of the connector halves, or terminals not fully seated in the connector body.  
     
    Inspect for improperly formed or damaged terminals and test for incorrect terminal tension.  
     
    Inspect for poor terminal to wire connections including terminals crimped over insulation. This requires removing the terminal from the connector body.  
     
    Inspect for corrosion or water intrusion. Pierced or damaged insulation can allow moisture to enter the wiring. The conductor can corrode inside the insulation with little visible evidence. Look for swollen and/or brittle sections of wire in the suspect circuits.  
     
    Inspect for wires that are broken inside the insulation by gently pulling on suspect sections of wiring.

Throttle Position Sensor

Specific to:

Chrysler Sebring 2008-2009

Dodge Avenger 2008-2009

A properly operating TPS should display a linear -sweep- of the entire throttle range, and should not exhibit any voltage drop or signal break. If the feedback signal is not within the specified range, additional diagnosis is required in order to determine the proper function of the TPS, or if a fault exists in any related sub-systems.

Throttle Position Sensor Strategy

Specific to:

Chrysler Sebring 2008-2009

Dodge Avenger 2008-2009

The TPS provides a linear input signal to the Powertrain Control Module (PCM), which is used to monitor the throttle position. The TPS monitors the entire range of throttle opening from 0.5 volts DC (0%) 4.5 volts DC (100%). In modern drive-by-wire throttle control systems, the TPS provides data to the PCM in order to calculate the desired throttle position, in addition to air-fuel mixture, ignition timing, fuel injector pulse width, and transmission/transaxle gear position.

The TPS utilizes positive coefficient logic: as the accelerator position is increased, the voltage is increased.
