We were having problems with our 2002 Toyota Rav4 which we bought used. Everything was working fine for the first month that we had it, but then we began to have problems. It wasn't acting right. It would sputter, stall while I was driving but it would crank right back up, but a few minutes later, stall again, It also wouldn't accelerate right. The check engine light went off and on also. It started around July 4th. We went to get it scanned and the code for the CPS A circuit #P0340 came up. After replacing it twice and testing it, it continued to act up. So our mechanic tested everything. He checked the wire harness, checked for any type of wiring problems. He came to the conclusion it was the ECM because when the car was cool, it ran great, the moment it was hot, the ECM would be hot and the car would start acting up. He found a way to cool the ECM which made the car run fine. It was in the shop a week because of all of this. ECM was just replaced and they did some test runs. No problems when they drove it 3 times to double check and they also let the engine get hot. It seems to be running great, no sputtering, stalling, etc. But 30 minutes to an hour after leaving the shop, we are getting the code again even after having all sensors checked, wiring, etc. What could be the problem?
have the same problem?
