    P0335, I installed a new crankshaft sensor to no avail. Checked voltage and am getting 0 at the connector so removed the connector to test the wires and still no voltage. The air intake sensor is running at 9v and no other codes are on at this time. I can’t locate a new sensor plug for the crankshaft and I can’t find the end of the wires for the crankshaft. Anyone have a wiring diagram or any new ideas to try?

    You can access factory repair manual info at techinfo.toyota.com

    That will show you how to check continuity of the wiring harness between the sensor and the engine control module.

    Also, you need to use an oscilloscope to evaluate the signal produced by the crankshaft sensor as the engine is spinning.

    So changed out the sensor and the downstream connector and now it’s still throwing that code in addition to, c1259 and c1310

    IMG_3513.JPG IMG_3514.JPG IMG_3515.JPG Here's some diagrams that may help you. Looks like the cam position C1 and crank position C7 share a pin on the ecu and split at junction connector J14. J14 looks to be located behind the glovebox.
