So my car’s been out of service for a week I have a 2011 Toyota Prius. At first, I got the code P0343, which was to change the camshaft sensor, so I changed the sensor and after I changed that I started driving and my car shut off and lost power within 5 minutes of driving and I also had to check hybrid system message. I still have the P0 343 code as well as the check hybrid system message. What is going on? Does anyone have any clues on what’s going on? Do I have to reset the sensor or what’s going on with my hybrid message? Warning light, it also starts for a few seconds and then it shuts off at times when I try to start it. I also have a video and picture of the codes and what happens when I started it but it’s not letting me upload it to the site
welcome! the upload function is broken. only solution is to post it elsewhere that can be linked to. you may need a prius aware scanner like the dealers have for complete codes. hybrid pit has a good rep in your area. if you want to diy, tech stream is the toyota code reader, but there are others if you search. did you get the sensor from a dealer? there are a lot of counterfeit parts out there. all the best!
That's the main mistake, thinking a trouble code actually tells you what to change to solve the issue. No code from a car ECU can be that all-knowing. The P0343 code is the ECM telling you it saw a high-level input (4.7 volts or more) arriving at the ECU from the camshaft sensor, for four seconds or more, when it really should be flipping between high and low voltage as the cam rotates. That might be seen because of a problem in the wiring to the sensor, or in the sensor itself, or in the ECM. The section for P0343 in the repair manual has eleven pages of advice for how to find out what, in your car, is causing the > 4.7 volt reading that gave you the P0343. Toyota Service Information and Where To Find It | PriusChat That's the kind of thing that happens when someone interprets a trouble code as if it were some all-knowing instruction to go change some part. The problem now is that whatever was causing the P0343 in the first place hasn't been found and fixed yet, and once that happens, you'll have a fixed P0343, and a new camshaft sensor into the bargain.
I had the same issue after having some work done, after alot of diagnosing I found a sensor was unplugged on the top of the engine right side... the camshaft position sensor I believe. Looked completely plugged in until I touched it. runs fine now after clearing codes.
