im working on a 2004 grand cherokee and it has a p0122 code its a tps circuit low voltage. whats that mean and how do i fix it?

 

It means that you back probe the TPS connector with a digital volt meter and try to adjust the voltage to specifications. (Not really hard to do) you need to download a PDF file off the Internet and get detailed instructions also a few applicable tools which you already have in your toolbox. Just Google TPS adjustment and find your jeep. If the TPS wont adjust get a new one (Around 40-60 bucks). They are easy to replace.

 

i tried a new one and the code came right back. i didnt kno there was an adjustment. ill look into it. thanks
