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)

- Measure the resistance between the terminals of camshaft position sensor connector.
Standard:

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)

- Disconnect the c1 camshaft position sensor connector.
- disconnect the e3 ecm connector.
- check the resistance between the wire harness side connectors.
Standard (check for open):

Standard (check for short):

- Reconnect the ecm connector.
- reconnect the camshaft position sensor connector.



3 Check sensor installation(camshaft position sensor)
- Check the camshaft position sensor installation.


4 Check camshaft timing gear assy(teeth of plate)
- Check the teeth of the signal plate.


Replace ecm

Dynamic radar cruise control
This dynamic radar cruise
control detects the presence
of vehicles ahead,
determines the current vehicle-
to-vehicle distance, and
operates to maintain a suitable
distance from the vehicle
ahead. The desired
vehicle-to-vehicle distance
can be set by operating the
vehicle-to-vehicle distance
switch.
