2003 CR-V Throttle Position Sensor replacement

I used a code reader to find the problem, purchased the sensor, and now I am discovering that it will mean removing the throttle body? I can do it but I want to be sure that is the problem before I start.I have read that- TP sensor is often missdiagnosed, throttle body has to be replaced (can't remove the TP sensor), and that it may be a loose/dirty conection. The idle is irregular, the rpm's are up too high at times, loss of power.........any feedback would be helpfull at this point. I have even been told that I may just need to clean the throttle body out due to possible fuel contamination. Please help...eager to get started on something!

    Throttle position sensor - Throttle body

    @ 90K mile svc, honda dealer read diagnostic code p0122 indicating an issue with the throttle position sensor "A" low voltage. They also said that it must be replaced with the Throttle Body. Net-net $990.00 Plus tax.

    Looking for alternative (read cheaper) solution.

    Problem actually on Mom's vehicle. I have added Seafoam Fuel systme cleaner and used Carb cleaner spray. Some apparent benefit right away and will report further.

    One symptom that remained was a seemingly hard (at least rough) downshift into low gear immediately prior to coming to a complete stop. The other symptoms that mother described (that apparently have abated somewhat after the first gas treatment and a 90 mile roadtrip) were hesitation & rough upshifts. I suspected that she has gunked up her fuel system as she has put only 3K miles on vehicle since purchase with 87K 9 months ago. The road trip was with STP additive, Seafoam and spray done after trip, too soon to tell. I told her that her problem was likely caused by bulid up of deposits and hopefully reversable with treatment and some road miles. Comments anyone?

    Update on Moms TPS problem. After running a tank w/ seafoam & using carb cleaner spray as recommended by mrgreenz, the engine light went out and the symptoms went away... for a while anyway. Now the engine light is intermittant and a code check at AAP gives the same P0122. Symptoms are very mild when present at all.

    Further investigation revealed honda technical service bulliten 04-008 (2002-2004 CRV - All) that states "The throttle position sensor in certain throttle bodies becomes contaminated due to a manufacturing defect" (The seafoam and carb cleaner probably alleviated some of this contamination.)

    While the bulliten allows for the possibility of Honda "good-will" for out-of-warranty repairs for this problem, I was told by the regional service manager that Honda had removed his previously permitted discretion on allowing goodwill up to $500. on any particular case, and had also set a 75000 mile limit for consideration at upper levels.

    True or not, I just know that I ain't getting any. I will soon be replacing the sensor only and will post when complete. Maybe next week?

Try cleaning the IAC (Idle Air Control valve.) by buying spray carb cleaner and removing the air cduct from the engine. On the fuel system side look into the hole and try to locate 2 holes on the side . With the engine running at about 1200 rpms, spray about 10 seconds worth of cleaner at the 2 holes. Turn the engine off. Let the cleaner soak. Then repeat procedure. The IAC can also be removed and cleaned if you wish.

Replace throttle position sensor in 2011 Chevy Malibu 4 cyl.

If you had the job done at a garage, take it back. You paid good money for a part that wasn't bad. Lets take yours for instance..A TPS code. Probably read from a code reader. Replace the TPS and still have the code. There are 3 things to check for any sensor, any code. The sensor, the wiring , and the computer/PCM. A code reader only gives you a place to look, NOT the solution..

Replace Throttle Position Sensor on my 2003 Chevy Suburban

Disconnect the wire connector to the sensor then remove the 2 screws and remove the sensor then put new one on and reset the computer with a code reader or a scan tool or take it to your local autoparts store (advance auto,autozone,ect.) and they can reset it for you at no charge to you.

2003 dakota pops back through carb/throttle body (misfires). Code reader gives a P2135 code. What do you think is the problem? Seem to happen after a drive and then sits a while. After it get up to...

P2135 is a throttle position code. If it is popping through the intake that is an indication that it is lean ( not enough fuel) I would risk the cost of a Throttle position sensor and replace it.

2003 Honda Accord - RPM's go high around 30-40mph

This problem does sounds like it could be a badThrottle position sensor because your transmission is fully electric and it depends on the signal of the throttle position sensor and the vehicle speed sensor to operate. I would recommend that you have this vehicle put on another computer at another location like AUTO-Zone they will check code for FREE and get a second opinion. Just to make sure that the code is NOT they same and also make sure that sensor was actually changed. If it was and the code is still the same and that's the only code in the computer then there is a problem with the wiring that connects to this sensor. Good Luck and contact if you need more help.Thanks for using FIX YA

Issue with throttle control on my 2003 Maxima

I discovered that its the throttle body sensor. Its not sensing the postion of the foot pedal. The throttle body has a sensor that is linked to your gas pedal via a cable. The spring that the repair man mentioned could be the issue. The sensor then communicates to the computer the position and then computer then applies fuel, the mass air sensor then will communicate to the computer and the computer will then allow more or less air to fuel ratio. So if your stomping on the gas and there is not any response, then your throttle body sensor is most likely going out.
