  • Unfortunately I haven't had that problem before, usually replacing the sensor takes care of the problem. According to the factory service manual, if the sensor is OK, then the next step is to replace the Crankshaft Position Sensor. Before you replace the sensor, make sure you the sensor connector is firmly connected.

  • i have a code of P1078. mechanic is recommending to replace both camshaft position sensors and crankshaft position sensor. also recomends to replace the exhaust valve timing control position sensor bank 1 and 2.

  • If you only have the P1078 code, you should replace just the exhaust valve timing control position sensor bank 1. The sensors are not a maintenance item; the sensor will not wear off with time, like a set of brakes or belts. Some customers prefer replacing all the common sensors to prevent too many trips to the mechanic, but it will be up to you.
