Idle position sensor

I removed the idle position sensor from the throttle body. Now its idling rough on initial start. The check engine light illuminated, an scan tool showed a P0102 code. The check light went out the next day without doing anything.

My 96 nissan altima dies at idle


Could be a dirty throttle body, vac leak, or a defective idle air control valve. The computer adjusts idle speed by controlling the amount of air entering the throttle body via the control valve.
Is the check engine light on ?

95 taurus idling too high like it is stuck wide open


Several issues can cause this problem, either singularly or in combination.. Check the throttle body for dirt and sticky carbon deposits. clean the throttle body using a spray can carburettor/choke cleaner, and with the throttle valve held open, wipe out the bore of the throttle body with a solvent soaked clean rag. Make sure the throttle valve is not sticking any where in the throttle travel between closed and open.

Next, check the idle air bypass valve that is mounted on the top of the throttle body, for dirt and carbon deposits inside that can cause the idle air bypass valve to stick in an open position. Clean the inside of the idle air bypass valve with carb cleaner.

If the ignition timing is over advanced, (Specifies timing advanced is10 degrees Before Top Dead Center, with the in-line spark out plug removed from the spout connector housing, and with the idle speed set to the idle RPM shown on the emissions sticker under the hood, with the engine fully warmed up,) use a timing light to check and set the ignition timing to specification.

The throttle position sensor must be installed on the throttle body using the required method or the idle speed will likely be excessively high. Beginning with the battery negative cable disconnected from the battery, and with the throttle position sensor removed, place the sensor in position on the throttle body with the drive tabs on the sensor placed after the drive tabs on the throttle shaft, the holding the sensor on the throttle body, rotate the sensor counter clockwise to align the mounting screw holes in the sensor and the throttle body, Insert the sensor screws into the senor screw holes, into the threaded holes in the throttle body and tighten finger tight. Carefully center the sensor on the sensor screws, then tighten the screws firmly without over tightening. Reconnect the sensor electrical harness connector.

Inspect the throttle valve idle stop screw adjustment that holds the throttle valve open slightly, to prevent the throttle valve from touching the throttle body bore surface with the throttle closed, and the accelerator pedal unpressed.

2000 grand cherokee laredo, 4.7 engine, very rough idle. all cylinders do not seem to be firing (not positive on this). have to play with gas to keep jeep running but has very rough idle.


If your engine light is on, please get a free scan at your local parts chain and send us the trouble codes. Recommend you start by removing the idle air control valve and cleaning the valve and passages as well as the throttle body with carb cleaner. Check the operation of the valve by hooking up the connector and turning on the key (do not start the car) while it is off the engine to see if it actuates. Please let me know if you have questions.

  1. Remove air duct and air resonator box at throttle body.
  2. Disconnect electrical connector from IAC motor (#4 in picture).
  3. Remove two mounting bolts (screws).
  4. Remove IAC motor from throttle body.
  5. clean valve, passages, and throttle body (#2)

Idle at 250 rpm


Idle Speed Control (ISC) Motor OPERATION Eagle Throttle Body Fuel Injection (TBI) System NOTE: The Eagle TBI system is used only on 2.5L Premier engines. The Idle Speed Control (ISC) motor is mounted to the throttle body and controlled by the PCM. The throttle lever rests against the initial adjustment screw of the actuator (plunger). The idle speed is not adjustable. The initial adjustment screw is only used to establish the initial positioning of the actuator when the ISC motor has been replaced. The actuator extends or retracts to control engine idle speed and to set throttle stop angle during deceleration. Based on inputs from the various engine control system sensors and switches to the PCM supplies current to the ISC motor to adjust the actuator position for the particular operating conditions.

Saturn 1999 sl Engine has a high idle speed. How do I find, replace, inspect IAC?


The Idle Air Control valve is located on the throttle body. If you follow the intake tube from your air filter all the way back to the intake manifold, where the intake tube connects to is the throttle body. Remove the intake tubing and you can see the throttle body.

There are two sensors on the throttle body and a vacuum line. You'll see two harnesses going to the throttle body, one is the IAC.

However, a quick diagnostic check can be done without touching the throttle body to confirm your problem. If the car has a normal idle when initially started but then rises to a higher idle and stays there BUT then if you were to shut the car off and restart it and it comes back to normal that is the Throttle Position Sensor (TPS). This is also located on the throttle body (the other sensor to the IAC). If it is the IAC it will be high and maybe fluctuate a bit.

I got code p2176 I changed out the tps still got same problem did not have this problem with other engine just changed engine out now cant seem to get this code off causing the car to rough idle and low...


P2176=Throttle Actuator Control System - Idle Position Not Learned
Did you use all you old sensors,or is some of them from the new engine,I would swap out the IAC sensor or check for wires not hooked up.
If it can't relearn to idle the Idle air control might be different then your old one,but its not registering with the computer
