Toyota Corolla Repair Manual: Inspection procedure
Hint
:
- if different dtcs related to different systems that have terminal e2
as the ground terminal are output
simultaneously, terminal e2 may be open.
- 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 Read value of hand–held tester or obd ii scan tool(engine
coolant temperature)
- Connect the hand–held tester or the obd ii scan tool to the dlc3.
- turn the ignition switch on and push the hand–held tester or the
obd ii scan tool main switch on.
- select the item ”diagnosis / enhanced obd ii / data list / all /
coolant temp” and read
its value displayed on the hand–held tester or the obd ii scan tool.
Temperature: same value as the actual intake air temperature.
Result:

Hint
:
if there is an open circuit, the hand–held tester or the obd ii scan tool
indicates –40 °C (–40°f).
If there is a short circuit, the hand–held tester or the obd ii scan tool
indicates 140 °C (284°f) or more.


2 Read value of hand–held tester or obd ii scan tool(check for
open in wire harness)

- Disconnect the e2 engine coolant temperature sensor
connector.
- connect terminals 1 and 2 of the engine coolant temperature
sensor connector on the wire harness side.
- turn the ignition switch on.
- select the item ”diagnosis / enhanced obd ii /
data list / all / coolant temp” and read its value
displayed on the hand–held tester or the obd ii scan tool.
Temperature value: 140 °C (284°f) or more
- reconnect the engine coolant temperature sensor connector.



3 Read value of hand–held tester or obd ii scan tool(check for
open in ecm)

- Disconnect the e2 engine coolant temperature sensor
connector.
- connect the terminals thw and e2 of the e3 ecm connector.
Hint
:
before checking, do a visual and contact pressure check on the
ecm connector.
- turn the ignition switch on.
- select the item ”diagnosis / enhanced obd ii /
data list / all / coolant temp” and read its value
displayed on the hand–held tester or the obd ii scan tool.

displayed on the hand–held tester or the obd ii scan tool.
Temperature: –40 °C (–40°f)
- reconnect the ecm connector.
