Toyota Corolla Repair Manual: Inspection procedure

Hint

: read freeze frame data using the hand-held tester or the obd ii scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the airfuel ratio was lean or rich, etc. At the time of the malfunction.

1 Inspect camshaft position sensor(resistance)

  1. Measure the resistance between the terminals of camshaft position sensor connector.

Standard:

Notice:

Notice

: cold and hot shown above mean the temperature of the coils themselves. Cold is from 10 c (14 f) to 50 c (122 f) and hot is from 50 c (122 f) to 100 c (212 f).

2 Check harness and connector(camshaft position sensor  ecm)

2 Check harness and connector(camshaft position sensor ecm)

  1. Disconnect the c1 camshaft position sensor connector.
