Thread: p0122 TPS low voltage

  1. #1

    Default p0122 TPS low voltage

    There are many posts on this subject and I wanted to mention my situation. 2003 CRV gets trans fluid changed. 4 miles outside of the shop the engine light come on and the trans is shifting hard. Downshift hard and upshift late.
    P0122 is read from the dealer. There is a service bulletin about this: http://www.crvownersclub.com/TSBs/2005/04-008.pdf

    I asked dealer if the wires are clean. "yes"

    They recommend the throttle body replacement. $1000

    They refused to replace just the sensor which is $100 part.

    Solution: buy a computer to read the error codes $130, gumout throttle cleaner $5

    clear the error with the computer.
    remove the airline to the throttle body (one screw on a clamp)
    spay the gumout cleaner into the TB(follow the direction on the bottle, may need your wife/husban to step on the gas)
    let the car idle for ten minutes
    let the engine cool

    ready to drive.

    The CRV now drives perfectly. Do yourself a favor and clean the TB before you replace it for $1000. If my fix does not last then I will replace the sensor with an aftermarket TPS. All you need is a voltmeter and hacksaw to do this. Common sense must prevail! F the dealer.

    How has that worked out so far? Has the CEL returned?

    After several more weeks with no problems the Throttle body was replaced on a saturday afternoon in my driveway. All you need are some wrenches and a clamp for the radiator line.

    Why, I thought you said the fix was good ?

    Did you get a used one ? What about the gasket, does it come off clean or did you just use some paste?
