6-58 ENGINE GENERAL INFORMATION AND DIAGNOSIS
Step
4 Check TP Sensor and its Circuit.
1) Turn ignition switch ON.
2) Check voltage at terminal E19-16 of ECM
connector connected, when throttle valve is
at idle position and fully opened. See Fig. 2
and 3.
Dose voltage vary within specified value linearly
as shown in figure?
5 Check TP Sensor.
1) Turn ignition switch OFF.
2) Disconnect TP sensor connector.
3) Check for proper connection to TP sensor
at each terminal.
4) If OK, then measure resistance between
terminals and check if each measured value
is as specified below. See Fig. 4.
TP sensor resistance
Between 1 and 2 : 4.0 – 6.0 kΩ Ω Ω Ω
Between 1 and 3 : 0.02 – 6.0 kΩ Ω Ω Ω , varying
according to throttle valve opening.
Are measured values as specified?

Action Yes
If voltmeter was used,
check terminal E19-16 for
poor connection.
If OK, substitute a known-
good ECM and recheck.
High resistance in "Lg/R",
"Lg" or "B/Bl" circuit.
If wire and connection are
OK, substitute a known-
good ECM and recheck.
No
Go to Step 5.
Replace TP sensor.
