The most likely causes of codes that relate to intermittent faults include poor connections in both live and ground circuits, as well defective switches, relays, and sensors. What are the symptoms of the P0349 code? If the color of the sensor is black then it should qualify for the recall. Depending on the engine or emission package, the vehicle may use a total of either 2 or 4 sensors. The last thing you want is to get stuck in the middle of the road.

By the way, this is a two wire induction sensor sure you figured that out. There is nothing to do but watch in horror as a vehicle approaching at 70 miles an hour rear-ends you. Older Cars — Over time, plastic and rubber tends to become brittle and less flexible, which can lead to connector breakage and wire insulation damage. Crankshaft Position Sensor A Circuit Intermittent P0340…. Sensor B indicates that the malfunction is occurring with the camshaft position sensor circuit that pertains to the exhaust camshaft. Other product and company names shown may be trademarks of their respective owners. So I changed that spark plug again.
My thinking is the a sensor is bad, either the cam or crank but i'm not an expert. Then I cleaned my throttle body and mass airflow sensors because I was at a loss praying the valve is not opening.
