Question about 2003 Honda CR-V

6 Answers

RE: 2003 Honda CR-V Malfunction light came on, it was not the gas cap. Noticed irregular idleling,and rpm too high at times. Sometimes it would act fine and light would not be on. Read code at the auto store = Throttle Position Sensor So I purchased the sensor and went home to discover the only way to get to it is by removing the throttle body. Did research on internet and read that I may not be able to remove TP sensor from throttle body. I may have to purchase new throttle body also? This problem all started 2 days after filling up a very low gas tank...I know that dirt/gunk can be sucked up into the engine from a low tank. Can that effect the sensor or throttle body? I know there is a very effective throttle body cleaner available. I just do not know where to start and am eager to fix my vehicle. If you have any feed back, I will be grateful. Please help me get started somewhere. Thanks

    I had the code checked at Schucks and it said it was the throttle position (TP) sensor. Should I get it checked somewhere else also?
    I purchased the TP sensor already.

  • moonscalded Feb 16, 2009

    Do not remember exact code #. Code reader said TP sensor right on the screen.
    I do not understand why it runs fine with no light on and then 5 mins later can run bad and light comes back on. Can the sensor be "going" out? Or is there fuel contamination?

  • moonscalded Feb 16, 2009

    So there is no question that it is the TP sensor if that is what the code reads?
    And do I just remove the throttle body and the old sensor will be able to be removed to put in the new one?

  • moonscalded Feb 16, 2009

    not at a garage, at a auto parts store.

  • moonscalded Feb 16, 2009

    Thank you for the advice. I still do not know if when I can just remove the TP sensor from the throttle body without any probs. Is the TP sensor built in to the throttle body?

  • moonscalded Feb 16, 2009

    Thank you but I still am unsure where to start....Re: Tp sensor and throttle body
    Manual says TP sensor cannot be replaced.
    Is it all in throttle body? Do I have to buy a new Throttle body?

  • moonscalded Feb 16, 2009

    If they are not sold seperatly then how did I manage to purchase one?

    So the job is impossible for me to do myself?

  • moonscalded Feb 16, 2009

    http://passwordjdm.com/Blox-Racing-Throt... here is a link to a site selling the Throttle Position Sensor seperatley. I guess I will have to try it. I will let you know how it works out.

    yes it is built in to the throttle body. its pretty complicated to change out but i would try the addatives first and the go on from there .

  • Ronnie Houston Feb 16, 2009

    if it says it cant be replaced then you have to buy a new threootle body....thats the way they are making them these days and why i told you to try to use the throttle body cleaner first. you will eventualy have to buy a new throttle body even if the cleaner works for now unless you use it on a regular basis

  • Ronnie Houston Feb 16, 2009

    you can do the job yourself but if the book tells you that you have to change out the whole hrottlebody and that is the only way to change the part you bought i would think that the book wouold be right. you can buy a part for anything .the parts houses carry parts of all kinds and you can buy what you think you need only to find out it wont work because its built into the threottle body. good luck with it my friend i think youll find youll need it

I would definitely recommend changing the sensor if thats the code you are given. You can buy the part at any parts store or at www.rockauto.com If you need any other assistance please let me know. Also please take a moment to accept and rate my solution accordingly.
Thank you,
Lee

    they are not sold separately due to the calibration involved it is kind of costly. Most dealerships I believe parts alone are about 800$ though someone with the know how could possibly repair so your best bet is to have a mechanic dive you an estimate. If you need further assistance please let me know.
    Thanks,

If there is debris in the gas tank, this will clog the fuel lines and the fuel filter before getting to the TPS.

If you had it checked at a garage I assume tehy checked already the fuel lines. If not you can check the fuel filter and blow into the fuel hose in direction from engine side toward tank side, otherwise you push in more debris.

Code will read the same anywhere. The info is coming from your car - their diagnostic tool is merely reading the info.
Change the sensor, and drive the car to the store and have them reset it.

Thanks for using FixYa - a FixYa rating is appreciated!!

    you would do well to purchase a couple bottles of gas line antifreeze.... you may have stirred up water in the gas tank... this will **** up the water from the gas

The 1st thing u need to do is have the system tested for a trouble code that it will have if the light is on, any Kragen auto or Autozone will do this for free, it may be a Throttle position sensor doing this, or a Mass Airflow sensor but there are over 100 malfunctions that turn the check engine light on, so I will need the code to assist u further.

    The tps code is the key to this problem replace it, u may also need to clean the intake, use the following procedure and product to do this. always disconnect the battery after a new emission part is replaced.

    Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

2003 Honda Cr-v has the mal light on


You have to get the code read first. There are hundreds of cause for the MIL (malfunction indicator light). Once you know the code then we can help you. Most local auto parts store are more than happy to read the code for free. Don't ask them tho because they are parts people and are not technician. If they were they would not be selling parts. Don't ask a mechanic either because they a tendency to guess. Ask me again I will tell you what to check ones you know the code. I am an expert on OBDII.

Malfunction indicator lited repeatedly


Probably is the throttle position sensor is bad. If you through several cycles and the computer does not see a problem then it will clear the codes until the problems exists again. That is why you see the light go out. You probably have a problem with the TPS.

yes, this is the case of a failed throttle body, in which case it needs replaced, the car is getting too much fuel causing the high idle. this needs replaced asap. you could proably find a small independant honda shop that could do the work for less.

2003 CR-V Throttle Position Sensor replacement


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.
