This problem alone will cause the engine to stall. 5. Remove the Sensor Mount Bolt. SPONSORED LINKS. Most crankshaft sensors will have just one mount bolt which will typically be a 10mm bolt. Use a small wrench or socket to remove the bolt by turning it counterclockwise and place to the side for safe keeping. The voltage should be between 13.5 and 14.8 volts with the engine running. Switch on the accessories in your C4, for example, headlights, AC fan at full speed, and interior lights. The voltage should remain around 14 volts. If it drops and remain below 13.5 volts, it indicates a problem with the current supply from the alternator. OBD2 Code P0338 Citroen definition: The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. Contrary to local garage diagnostics Taunton Citroen diagnosed a sensor fault rather than pump failure. They say the sensor believes ad blue temperature is -40 C and won’t inject as it believes it’s frozen… They past report to Citroen U.K. who have offered 42% contribution to parts cost. ONLY. NO Labour. If there is no voltage to the pump, or if the pump is in fact running, then you probably need to get a Lexia diagnostic tool connected to the car to find out what the Engine management system thinks it is doing. wurlycorner.

The Crankshaft Position Sensor (CKP) works in conjunction with a 24X reluctor wheel mounted on the rear of the crankshaft. The CKP sensor has a B+ power supply, a ground, and a signal circuit. As the crankshaft rotates, the reluctor wheel teeth interrupt a magnetic field produced by a magnet within the sensor.
