I have a 2007 Toyota Corolla 1.8L A/T. ~96,000 miles
- I had an intermittent P0741 'Torque Converter Clutch Shift Solenoid Performance' (Sometimes a P0341 'Camshaft Position Sensor 'A'')
- It died on me while driving under heavy acceleration and would not turn on.
- I was able to get it running and changed the shift solenoid. (I tested all three and changed the bad one)
- I thought I fixed the issue but then I got a check engine light within the same day. Got a P0341 with a P0420.
- I changed the camshaft position sensor and I ran the codes and only had a P0420 code.
- Yesterday I was getting onto the ramp and accelerating heavily and the car died on me on the highway. I had to get it towed off the highway. Once off the highway, scanned the codes and it was only a P0340 code (not P0341). I disconnected and reconnected the camshaft position sensor and the car was able to get up and running. I barely got home and ran the codes and the vehicle died again, but I got a P0335, P0420, and B2780('Key Switch "OFF" malfunction').
Its difficult to keep track of everything that has happened with this car, in short, the codes are P0741, P0341, P0335, P0420, P0340, and B2780 and these codes are never consistent together.
I could really use some good quality help, I dont really know a good mechanic or trust mechanics here in NYC. Im pretty hands-on but after the vehicle shut down on me on the highway, I realized this issue is very serious and needs to get resolved.
I know there is a recall for the ECM but Toyota said my VIN number did not fall under the vehicles affected.
I also reset the ECM by the way Scotty showed in the videos. No fix.
Greatly Appreciated,
Manny
Wow,you've got a pile of codes and problems to raise a lot of questions. Has there been something that compromised your electrical system - accident, rodents, weird previous owner's alarm system? What type/level of scanner are you using? Are you using a site like this to aggregate symptoms and causes like https://repairpal.com/obd-ii-code-p0420
The electrical system seems fine. I do have a viper alarm system but that was installed years ago and never had issues with it. Its a daily driver, so no rodents. Im using a Blue Driver and using the corolla service manual to troubleshoot the codes.
Your electronics are falling apart.
Check wiring and take it to a car electrician...
Maybe your ground is bad or harness is damaged
This type of failures is characteristic for a Citroen with French electonics, not a Corolla. I believe it's just an exposed wire, weak battery, or dead ECM...
I replaced the battery, I checked the grounds. Still no fix. It seems like the camshaft position sensor that I replaced has a resistance that is not within parameters per the service manual. (Cold: 1,630-2,740 Ohms ; Hot: 2,065-3,225 Ohms) It reads 3,300 Ohms Cold. So looks like bad from stock. Will update. Apologies for the late response.
Kinda shocking considering that generation of Corolla is way better than its successor and it has under 100k miles.
I'm shocked as well. This car is a serious headache. Seems like its gonna be the ECM.
