INSPECTION
STEP ACTION YES NO
1 Was “ENGINE DIAG. FLOW TABLE”
performed?
Go to Step 2. Go to “ENGINE DIAG.
FLOW TABLE”.
2 Check TP Sensor and Its Circuit.
1) Connect scan tool to DLC with ignition
switch OFF and then turn ignition switch
ON.
2) Check throttle valve opening percentage
displayed on scan tool. See Fig. 1.
Is it displayed 2% or less?
3) Check throttle valve opening percentage
displayed on scan tool while opening
throttle valve from idle position to full open
position. See Fig. 1.
Is it displayed 96% or higher?
Go to Step 3. Intermittent trouble.
Check for intermittent
referring to “Intermittent

1) Disconnect connector from TP sensor
with ignition switch OFF.
2) Check for proper connection to TP sensor
at “P”, “Gr” and “G” wire terminal.
3) If OK, then with ignition switch ON, check
voltage at each of “P” and “Gr” wire
terminals. See Fig. 2.
Is voltage about 4 – 6 V at each terminal?
Go to Step 4. “P” wire open, “P” wire
shorted to ground circuit or
power circuit or “G” wire,
“Gr” wire open or shorted
to ground circuit or poor
C01-22 or C03-5
connection.

good ECM (PCM) and
recheck.
4 Check TP Sensor.
1) Check resistance between terminals of
TP sensor. See Fig. 3.
Between 1 and 2: 2.5 – 6.0 kΩ
Between 1 and 3: 170 Ω – 15.5 kΩ
Are measured values within specifications?
“G” wire open or poor
C01-10 connection.
If wire and connection are
OK, substitute a known-
