Manual tempro tp 800 heat pump

Throttle Position Sensor is located on the Throttle Body for the EFI intake. Mark position of old unit and try to match when installing new unit. Should be taken to garage to get proper adjustment of "TPS" at idle if your unsure of yourself.

Throttle Position Sensor Replacement
Remove the idle air control (IAC) electrical connector (1) from the IAC sensor (4).
Remove the manifold absolute pressure (MAP) sensor electrical connector from the MAP sensor.
Remove the water pump belt cover.
Remove the TP sensor retaining screws electrical connector (2) from the TP sensor (3).
Remove the TP sensor electrical connector (2) from the TP sensor (3).
May have video on youtube showing how to

Is the check engine light on , or any other lights ?

• Unique Idle Concerns:
  • Fast Idle
• Additional Drivability Concerns:
  • Diesels/Runs On

Note: If vehicle runs normally after the ignition key is turned OFF, check for damaged ignition switch, IGN RUN circuit short to power, VPWR circuit short to power, etc. Refer to applicable Wiring Diagram and/or Workshop Manual.
SYSTEM/COMPONENT REFERENCE (Section 5 Pinpoint Test unless noted)

• Base engine air leaks, including proper sealing of intake manifold and components/vacuum lines attached to intake air (such as the PCV, EGR or IAC valve/vacuum lines).

• Visual, Engine System - General Information Section 303 of the Workshop Manual.

• Verify engine operates at normal temperature.

• Visual (refer to Symptom Index, or Engine Cooling Section 303 of Workshop Manual, to diagnose any cooling system concerns that are present).

• Fast idle concerns:
• Key on, engine off, monitor TP MODE PID while wiggling TP sensor circuits. TP MODE PID can also be monitored during vehicle drive. With throttle closed, TP MODE PID must be C/T (closed throttle).

• TP Mode PID is not C/T with throttle closed: NOTE: At vehicle start, the TPREL will begin at about 1.25 volts, and count down to the lowest TP V value seen since engine start. If the TP V value goes below the "normal" range, then increases again, TPREL will set to the lower voltage. If TP V is about 0.04 volts greater than the TPREL value at closed throttle, the PCM will go into part throttle mode.
  
• Monitor TP V and TPREL PIDs for sudden changes while checking for intermittent TP circuit/connector concerns. Also check for loose/worn throttle plates. If no concern is found, GO to Z1 in Section 5.

• Intake Air System (air leaks)

• GO to HU1

• Idle Air Control (IAC) System

• GO to KE1

• Additional Testing

• GO to Z1

Do you know what these thing's are that I have listed above ? Mostly the TP - throttle position sensor . These are known to cause this type of problem . Has it ever been changed before ?

Throttle Position Sensor Replacement

1. Disconnect the negative battery cable.
2. Remove the generator.
3. Disconnect the throttle position (TP) sensor electrical connector.
4. Remove the TP sensor attaching screws
5. Remove the TP sensor
   
6. Remove the TP sensor O-ring seal
   

Installation Procedure

1. Install the TP sensor O-ring seal (7) on the TP sensor (6).
2. Install the TP sensor on the throttle body with the throttle valve in the closed position. Make sure the TP sensor lever lines up with the TP sensor drive lever on the throttle shaft.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the TP sensor attaching screws (5).
Tighten
Tighten the screws to 2 N·m (18 lb in).

4. Connect the TP sensor electrical connector.
5. Install the generator.
   
6. Connect the negative battery cable.

replace thermostat 1st if this dont work check the water pump tp make sure it is working properly. if this info is helpul pleae rate

Drain the coolant
Remove air cleaner assembly
Disconnect water hoses from radiator
Remove drive belt
Remove power steering pump
Remove water pump drive pulley
Loosten hose clamps on cylinder head tp water pump cooling line
Remove water pump mounting bolts and water pump

Just reverse these procedures to install new pump.
