FUEL SYSTEM (Programmed Fuel Injection}
6. TP Sensor Voltage at ECM
Connect the TP sensor 3P connector.
Turn the ignition switch ON.
Measure the voltage at the test harness termi-
nals.
Connection: A16 (+)- 816 (-)
Standard: *0.4- 0.6 V (throttle fully closed)
*4.2- 4.8 V (throttle fully open)
• A voltage marked
*
refers to the value when
the voltage reading at the TP sensor 3P con-
nector (page 5-19) shows 5 V.
When the reading shows other than 5 V,
derive a voltage at the test harness as fol-
lows:
In the case of a voltage of 4.75 V at the TP
sensor 3P connector:
0.4 X 4.75/5.0
=
0.38 V
0.6 X 4.75/5.0 = 0.57 V
Thus, the solution is "0.38- 0.57 V" with the
throttle ful ly closed.
Replace 0.4 and 0.6 with 4.2 and 4.8 respec-
tively, in the above equations to determine
the throttle fully open range.
Is the voltage within standard value?
NO - Faulty TP sensor.
YES - Replace the ECM with a new one, and
inspect it again.
