I replaced the crank and camshaft sensor within the last week, and code still comes up. When I drive it jerks every now and then when it adjusts speeds. Sometimes I'll drive and be below 40mph and it will cut off mid drive and I have to put in park, turn off and re crank. 261k miles.
-
If you new sensor and you have an intermittent problem, then it's very likely that the problem is with a broken wire or loose connector.
-
The wires are connectors are part of the engine harness, and replacing the harness can be very very expensive. Usually a technician search and repairs the broken wires, no parts may need to be replace. At this point I recommend haven a technician fix the problem for you.
