Throttle position sensor (TP sensor) on-vehicle
inspection
1) Disconnect negative cable at battery.
2) Detach purge valve chamber, and remove air cleaner outlet
hose.
3) Disconnect TP sensor connector.
4) 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
TERMINALS
Between 1 and
3 terminals
Between 2 and
3 terminals
NOTE:
There should be more than 2 k
between when throttle valve is at idle position and when
it is fully open.
1. Reference voltage terminal
2. Output voltage terminal
3. Ground terminal
5) Connect TP sensor connector securely.
6) Connect negative cable to battery.
Throttle position sensor (TP sensor) removal and
installation
Removal
1) Disconnect battery negative cable at battery.
2) Detach purge valve chamber, and remove air cleaner outlet
hose.
3) Disconnect TP sensor connector and 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)
1
are a little away from TP sensor screw holes (2) as shown in
figure and turn TP sensor clockwise so that those holes
align.
(a)
Tightening torque
TP sensor screw (a): 2.5 N·m (0.25 kg-m, 1.8 lb-ft)
2) Connect connector to TP sensor securely.
3) Connect battery negative cable to battery.
RESISTANCE
4.0 – 6.0 k
20 Ω – 6.0 k Ω , varying according to throt-
tle valve opening.
