Crankshaft Sensor Replacement in a 1995 Toyota Corolla

Since its release to the American marketplace in 1968, the Corolla has been one of Toyota's most simple and affordable vehicles. The seventh-generation Corolla -- 1993 through 1997 -- came about when the Corolla exited the subcompact class and entered the compact vehicle class. This was due to Toyota stretching the Corolla's wheelbase to 97 inches -- 7 inches longer than the original version. The 1995 Corolla had two engines available: a 1.6-liter four-cylinder and a 1.8-liter four-cylinder. Both engines used an electrical sensor -- crankshaft position sensor -- to relay the position of the crankshaft to the computer, so the computer could adjust ignition timing and the fuel injectors.

Instructions

1

Look on the driver's side of the engine, just above and a little behind the crankshaft pulley, and find the crankshaft position sensor.

2

Remove the crankshaft position sensor-retaining bolt, using a ratchet, socket and 6-inch extension. Trace the crankshaft position sensor's wiring upward until you find the wiring harness. Insert the blade of a flat-head screwdriver under the harness and pry it outward until its retaining clip unfastens from its bracket.

3

Press the locking button on the crankshaft position sensor's wiring harness, and pull the sensor's harness from the engine's harness. Remove the crankshaft position sensor from the Corolla.

4

Set a new crankshaft position sensor into the hole that the old sensor was in, and hand-thread its retaining bolt into place. Tighten the sensor's bolt to 6 to 7 foot-pounds, using a torque wrench, socket and 6-inch extension.

5

Plug the crankshaft position sensor's wiring harness into the engine wiring harness until it clicks into place. Line the clip on the rear of the sensor's wiring harness up with the hole in the bracket, and press the wiring harness toward the bracket until it clicks into place.
