Here today, gone tomorrow.. CEL code P0340 I've read through many posts, but none have helped as of today. I have a CEL code P0340 that comes & goes. If I'm on the highway, I can feel the engine hesitate, just before the light come on. So far I have... 1) Replaced the cam position sensor (and verified it's in there correctly) 2) Checked each wire on the sensor's connector for continuity and voltage 3) Replaced the crank position sensor 4) Cleaned the connectors After checking the wires & connectors this weekend, I cleared the code, but it returned the next day. It stuttered once on the highway, the light immediately came on & then it went back to running OK. Today, the CEL turned off?? I'm thinking about routing three new wires to the sensor connector. If I remember correctly, one is a ground, one is 12v positive with the key on & the last wire goes to the dme. I suspect an intermittent short. I really don't know. Is there anything else that would cause the sensor to flake out very infrequently? Last edited by weloveiggy; 08-30-2010 at 09:28 PM. |
