My 2004 dodge neon SXT 2.0L Manual is cutting out at 4000RPM and sometimes at 2000rpms we replaced the Throttle Position Sencor because the code popped up and still isn't right.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Hi Sharon:
Accordint with this, on 1991 Honda Accord 2.2L FI 4cyl the Throttle Position Sensor is located under hood, center, rear engine area, mounted on throttle valve assembly.


Fig. 1: The throttle body is attached to the intake manifold inlet. Always use a new gasket anytime the throttle body is removed-1990-93 Accord shown (others are similar)- CLICK HERE FOR IMAGE ZOOM The throttle position sensor is mounted on the side of the throttle body and is connected to the throttle shaft.
  1. Disconnect the negative battery cable.
  2. If necessary, remove the throttle body for access.
  3. The sensor may be removed by unscrewing the retaining bolts.
  4. Reinstall in the reverse order of removal. Make certain the sensor is correctly mated with the throttle body shaft.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.
