• Q: How to service the Crankshaft Position Sensor on 2007 Scion tC?

  A: The first step to service the Crankshaft Position Sensor involves disconnecting the negative battery terminal cable while allowing at least 90 seconds to pass before starting work because this time delay stops the Air Bag and seat belt pretensioner activation. Before starting remove the front fender apron seal RH as well as the fan and generator V belt then the generator assembly. To access the crankshaft position sensor you must first disconnect its sensor connector before removing the connector clamp while sliding out the wire harness from its wire harness clamp bracket and then removing the wire harness clamp together with the bolt and sensor. For sensor installation place the O-ring under light engine oil application before putting the bolt into its place while tightening to 9.0 N.m (90 kgf.cm, 80 in.lbf). The next step is to install the wire harness clamp followed by the connector clamp before connecting the sensor connector while securing the wire harness through the back of the timing chain cover rib. Put together the generator assembly while installing the fan followed by the V belt belonging to the generator and finish the installation with a cable connection to the battery terminal's negative side. Engine oil leaks must be checked while installing the front fender apron seal RH and the system requires initialization after reconnecting battery cables from the negative terminal.
