Toyota Corolla (E120): 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 air–fuel 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.
  2.  disconnect the e3 ecm connector.
  3.  check the resistance between the wire harness side connectors.

Standard (check for open):

Standard (check for short):

Standard (check for short):

  1. Reconnect the ecm connector.
  2.  reconnect the camshaft position sensor connector.

3 Check sensor installation(camshaft position sensor)

    Circuit description
    The vehicle equipped with abs detects a vehicle speed using the stability control ecu and wheel speed sensor. This sensor monitors a wheel rotation speed and sends the signal to the ecu. The stability control ecu converts these wheel speed signals into a 4–pulse signal and outputs it to ...
