1C-3 Engine Electrical Devices:
Throttle Position (TP) Sensor On-Vehicle
Inspection
S3RH0A1306008
1) Disconnect negative cable at battery and connector
from IAT sensor.
2) Remove air cleaner assembly with air cleaner outlet
hose and disconnect TP sensor connector.
3) Using ohmmeter, check resistance between
terminals under each condition given in table below.
If check result is not satisfactory, replace TP sensor.
TP sensor resistance
Between terminals “1” and “3”: 4.0 – 6.0 k
Ω
Between terminals “2” and “3”: 20
Ω
– 6.0 k
Ω
,
varying according to throttle valve opening.
NOTE
There should be more than 2 k
Ω
resistance
difference between when throttle valve is at
idle position and when it is fully open.
4) Connect TP sensor connector securely.
5) Connect negative cable to battery.
Throttle Position (TP) Sensor Removal and
Installation
S3RH0A1306009
Removal
1) Disconnect battery negative cable at battery.
2) Remove throttle body from intake manifold referring
to “Throttle Body Removal and Installation in Section
1D”.
3) Remove TP sensor from throttle body.
Installation
1) Install TP sensor (1) to throttle body.
Fit TP sensor to throttle body in such way that its
holes (3) are a little away from TP sensor screw
holes (2) as shown in the figure and turn TP sensor
clockwise so that those holes align.
Tightening torque
TP sensor screw (a): 2.5 N·m (0.25 kgf-m, 1.8 lb-
ft)
2) Connect connector to TP sensor securely.
3) Connect battery negative cable to battery.
Intake Air Temperature (IAT) Sensor Removal
and Installation
S3RH0A1306011
Removal
1) Disconnect negative cable from battery.
2) Disconnect lAT sensor coupler (1).
3) Remove lAT sensor from air cleaner case (2).
