Step
5 Check wire circuit.
1) Disconnect connector from ECM with igni-
tion switch turned OFF.
2) Turn ON ignition switch.
3) Check voltage between "GRY/RED" wire
terminal of TP sensor connector and body
ground and between "GRY/BLU" wire termi-
nal of TP sensor connector and body
ground.
Is voltage about 0 V at each terminal?
6 Check wire circuit.
1) Measure resistance between "C63-34" wire
terminal of ECM connector and "GRY/BLU"
wire terminal of TP sensor connector with
ignition switch turned OFF.
Is resistance below 5 Ω?
7 Check ground circuit.
1) Connect connector to ECM.
2) Check for proper connection of MAP sensor
at "ORN" wire terminal.
3) Measure resistance between "ORN" wire
terminal of MAP sensor connector and body
ground.
Is resistance below 5 Ω?
8 Check ground circuit.
1) Measure resistance between "C63-28" wire
terminal of ECM connector and body
ground.
Is resistance below 5 Ω?
9 Check TP sensor.
1) Check resistance between terminals of TP
sensor. See Fig. 2.
TP sensor resistance
Between 1 and 3: 4.0 – 6.0 kΩ
Between 1 and 2: 0.1 – 6.5 kΩ
Are measured values within specifications?

ENGINE GENERAL INFORMATION AND DIAGNOSIS 6-93
Yes
Go to Step 7.
Go to Step 8.
Go to Step 9.
"ORN" wire open circuit or
high resistance circuit.
Poor "C63-28" connec-
tion.
Substitute a known-good
ECM and recheck.
No
"GRY/RED" and/or "GRY/
BLU" wire shorted to
power circuit.
If wire are OK, substitute
a known-good ECM and
recheck.
"GRY/BLU" wire open cir-
cuit or high resistance cir-
cuit.
Go to Step 8.
Faulty ECM ground cir-
cuit.
If circuit are OK, substi-
tute a known-good ECM
and recheck.
Replace TP sensor.
