P1400

Component Description
The EGRC-solenoid valve responds to signals from the ECM. When the ECM sends an ON (ground) signal, the coil in the solenoid valve is energized. The vacuum signal passes through the solenoid valve. The signal then reaches the EGR valve.

When the ECM sends an ON signal, a plunger will then move to cut the vacuum signal from the throttle body to the EGR valve.




CONSULT-II Reference Value in Data Monitor Mode
Specification data are reference values.




ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and 32 (ECM ground).

DTC Confirmation Procedure

NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.

TESTING CONDITION: Always perform at a temperature above -10 °C (14 °F).

With CONSULT-II
1. Start engine and warm it up to normal operating temperature.







2. Select "DATA MONITOR" mode with CONSULT-II.
3. Maintain the following conditions for at least 5 consecutive seconds.

CMPS.RPM (REF): 1,000 - 3,400 rpm
B/FUEL SCHDL: 2 msec or more
VHCL SPEED SE: Suitable speed

4. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE" .

With GST
- Follow the procedure with "CONSULT-II ".

Overall Function Check
Use this procedure to check the overall function of the EGR temperature sensor. During this check, a 1st trip DTC might not be confirmed.

Without CONSULT-II
1. Start engine and warm it up to normal operating temperature.




2. Check the voltage between ECM terminal 103 and ground at idle.

Voltage: 0 - 1 V

3. Check that the voltage changes to battery voltage and returns to 0 - 1 V when revving the engine from idle to 3,000 rpm quickly.
4. If NG, go to "DIAGNOSTIC PROCEDURE".
