FUEL SYSTEM (PGM-FI)
MIL 8 BLINKS (TP SENSOR)
• Before starting the inspection. check for loose or
poor contact on the TP sensor 3P (Black) connec­
tor and ECM 33P connectors. then recheck the
MIL blinking.
1. TP Sensor Output Voltage
Turn the ignition switch OFF.
Connect the ECM test harness to ECM connec­
tors (page 5-14).
Turn the ignition switch ON and engine stop
switch
Measure the TP sensor output voltage at the test
harness terminals.
CONNECTION:831 (+) - A 18 (-)
STANDARD:
NOTE:
• A voltage marked * refers to the value of the
ECM output voltage (STEP 3) when the volt-
age reading shows 5 V.
When the ECM output voltage reading shows
other than 5 V, derive the TP sensor output
voltage at the test harness as follows:
In the case of the ECM output voltage ls 4.75
V:
0.4 X 4.75/5.0 = 0.38 V
0.6 X 4.75/5.0 = 0.57 V
Thus, the solution is "0.38 - 0.57 V" with the
throttle fully closed.
Replace 0.4 and 0.6 with 4.2 and 4.8 respec­
tively, in the above equations to determine
the throttle fully opened range.
Is there standard voltage?
YES
NO
2. TP Sensor Input Voltage Inspection
Turn the Ignition switch OFF.
Disconnect the TP sensor 3P (Black) 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
YES
NO
