FUEL SYSTEM (PGM-FI)
MIL 8 BLINKS (TP SENSOR)
• Before starting the inspection, check for loose or
poor contact on the TP sensor 3P (Blue) connec-
tor and ECM 33P connectors, then recheck the
MIL blinking.
1. TP Sensor Output Voltage
Connect the ECM test harness to ECM connec-
tors (page 5-16).
Turn the ignition switch ON and engine stop
switch " ".
Measure the TP sensor output voltage at the test
harness terminals.
Connection: B31 (+) – A18 (–)
Standard:
Is there standard voltage?
YES
NO
2. TP Sensor Input Voltage Inspection
Turn the ignition switch OFF.
Disconnect the TP sensor 3P (Blue) connector.
Turn the ignition switch ON and engine stop
switch " ".
Measure the voltage at the wire harness side.
Connection: Yellow/red (+) – Green/orange (–)
Is the voltage within 4.75 – 5.25 V?
YES
NO
3. TP Sensor Output Voltage Inspection
Measure the voltage at the test harness termi-
nals.
Connection: A9 (+) – A18 (–)
Is the voltage within 4.75 – 5.25V?
YES
NO
5-42
0.45 – 0.55 V (throttle fully closed)
4.72 – 4.77 V (throttle fully opened)
– Intermittent failure
– GO TO STEP 2.
– GO TO STEP 4.
– GO TO STEP 3.
– • Open circuit in Red/yellow wire
• Open circuit in Green/orange wire
– Replace the ECM with a new one, and
recheck; for Key Registration Proce-
dures (page 21-4).
