2. MAP Sensor Output Voltage Inspection
Connect the ECM test harness to ECM connec-
tors (page 5-14).
Turn the ignition switch ON and engine stop
switch "
".
Measure the voltage at the test harness termi-
nals.
The MAP sensor voltage should be changed
after engine started.
Is the voltage within 2.7 – 3.1 V?
YES
–
GO TO STEP 3.
NO
–
Faulty MAP sensor
3. MAP Sensor Output Voltage Inspection At Idle
Start the engine.
Measure the voltage at the test harness termi-
nals.
Is the voltage less than 2.7 V?
YES
–
Replace the ECM with a known good
one, and recheck; refer to Key Registra-
tion Procedures (page 21-6)
NO
–
Faulty MAP sensor
MIL 7 BLINKS (ECT SENSOR)
• Before starting the inspection, check for loose or
poor contact on the ECT sensor 3P (Black) con-
nector and ECM 33P connectors, then recheck
the MIL blinking.
1. ECT Sensor Output Voltage Inspection
Turn the ignition switch OFF.
Connect the test harness to ECM 33P connectors
(page 5-14).
Turn the ignition switch ON and engine stop
switch "
".
Measure the voltage at the test harness termi-
nals.
Is the voltage within 2.7 – 3.1 V?
YES
–
Intermittent failure
NO
–
GO TO STEP 2.
