DBerry Posted September 8, 2020 Share Posted September 8, 2020 So I got the wrench warning light and pulled a P2111 code. I researched that and cleaned the throttle body which was pretty gummed up qt 136,000 miles. It ran great for a couple days and the wrench light came back on, so I replaced the throttle body. That immediately caused P2112 and P2135 codes. I unhooked the battery for quite a while to clear the memory and then followed relearning procedures for the PCM. Same P2112 and P2135 codes. I thought maybe a bad throttle body, so I put the old one back on and relearned the PCM. Ran fine with no codes for a day and then the P2111 code came back and car would not get higher than 1900 rpm. So I put the new throttle body back on and relearned the PCM which resulted in the same P2112 and P2135 as I received before. Engine runs but will not accelerate. I am not finding much info online in these regards. I am wondering on a hybrid if disconnecting the negative on the battery low voltage battery clears the PCM memory or if the high voltage battery keeps it powered so that it does not clear the PCM’s memory. 1 Quote Link to comment Share on other sites More sharing options...
eGuru Posted September 8, 2020 Share Posted September 8, 2020 You are correct, the replacement ETB is defective. 1 Quote Link to comment Share on other sites More sharing options...
DBerry Posted September 11, 2020 Author Share Posted September 11, 2020 Yes, the replacement throttle body was in fact defective. The second one I received cured my problem. Thanks for pointing it out to me. 1 Quote Link to comment Share on other sites More sharing options...
VonoreTn Posted September 20, 2020 Share Posted September 20, 2020 Interesting. Good diagnostics guys. Did you get your money back on the first new TB? I can clear the codes with my OBDII code reader. I wonder what was wrong with the first new TB, I guess we will never know. It could have been one of several quality related things. 0 Quote Link to comment Share on other sites More sharing options...
DBerry Posted September 20, 2020 Author Share Posted September 20, 2020 Yes, I did get a refund on the first throttle body and the codes were cleared after I put the second new one on an reconnected the battery. 0 Quote Link to comment Share on other sites More sharing options...
