FUEL SYSTEM (PGM-FI)
2. MAP Sensor Output Voltage Inspection
Connect the ECM test harness to ECM connec-
tors (page 5-16).
Turn the ignition switch ON and engine stop
switch " ".
Measure the voltage at the test harness termi-
nals.
Connection: B9 (+) –A18 (–)
Is the voltage within 2.7 – 3.1 V?
YES
NO
3. MAP Sensor Output Voltage Inspection At Idle
Start the engine.
Measure the voltage at the test harness termi-
nals.
Connection: B9 (+) –A18 (–)
Standard:
Is the voltage less than 2.7 V?
YES
NO
MIL 7 BLINKS (ECT SENSOR)
• Before starting the inspection, check for loose or
poor contact on the ECT sensor 3P (Gray) con-
nector and ECM 33P connectors, then recheck
the MIL blinking.
1. ECT Sensor Output voltage Inspection
Connect the test harness to ECM 33P connectors
(page 5-16).
Turn the ignition switch ON and engine stop
switch " ".
Measure the voltage at the test harness termi-
nals.
Connection: B13 (+) – A18 (–)
STANDARD: 2.7 – 3.1 V (20°C/68°F)
Is the voltage within 2.7 – 3.1 V?
YES
NO
