Hi, my truck was not getting a spark. So most parts are old so i started with replaceing the coil, then crankshaft sensor, and it ended up being the computer. I replaced that and it started right up 1st time. Ran well for a couple of months ( I dont drive it much, just locale errands) and it started to sputter again then finally no spark again. The part was supposedly re manufactered. What would cause a computer to go out repeatedly. Or should I try replaceing the sensor again? I appreciate any help to resolve this. Thanks Tony
The truck will crank and run fine you go in a store come out want crank. Maybe sit there 15 or 20 minutes then it cranks up find it will run perfect for months then all of a sudden it's acting up again.
stalls while in motion rpms drop, engine stops while in motion no fix yet replaced camshaft sensor 3 times still has problem
Sometimes my 2007 dodge dakota does not start. When I get done working, I go to start my truck. It won't start, I wait 1 to 2 minutes it's starts up.I have battery, starter check. All are good. Could this be ignition problem
Truck just stops running while driving down the road. It will crank, but won't start. I have to let it sit for a bit and then it will start. Fuel pump has been replaced, as well as other fuel related parts. Now, the mechanic thinks it might be the ignition control module. Just don't want to put more money into it.
NO start and stalling while driving.
THE 3.7 v6 ENGINES must really have a problem because we have replace 2 cam shaft sensors in our 2006 Dodge
Dakota extended cab and we think it will have to soon be replaced again, this also has had to be replaced in our sons 2007 Dodge Dakota 4x4 maybe this should be checked into a little farther for recalls or something?
turns over but want hit a lick truck shows a p3040 code.
Have replace CMP 3 times in past 2 years, and still have the light, even though I erase it every time. Places i have researched indicate that the wire harness to the sensor could be bad, the crankshaft position sensor could be bad, or the PCM/ECU could need to be flashed. Trying to find a place to have the PCM flashed without going to the stealership.
intermit....start and stalling
I have replaced my camshaft sensor twice in the last year. Could this be the wires that are connecting it?
Won't Start, intermittent, check engine light on
The Durango twice in the last week has wanted to turn over but hasn't. It will start randomly later, there is no warning. Took it to advance and the code displayed no cam sensor reading.
4.7L V-8 SLT, Hard starting, engine 2 quarts low at normal 3,000 mile oil change. Dealership added dye to oil and found large oil leak at Cam Sensor. Replaced Cam Sensor, re-checked for oil leak, no leak noted. Next oil change after 3,000 miles, engine once again 2 quarts low. No error codes noted. Mechanic at Dodge dealership said he had never seen this type of oil leak and Cam Sensor failure before. He has worked at my dealership for 20+ years. Taking back to dealership for a second Cam Sensor replacement as no other engine leak was noted.
Still not fixed. Its been to several mechanics. All with different diagnosis. Each time the codes read differen.
oil leaking thru the sensor and filling harness, blocking the signal
Replaced three times. Each time after 8-9 months
Code 340 camshaft sensor intermittent
Needs replaced dealer says rough estimate $350. Part is 28.00 bucks what a steal!
