4-36 FI SYSTEM
“C14” TP SENSOR CIRCUIT MALFUNCTION
INSPECTION
DETECTED CONDITION POSSIBLE CAUSE
Signal voltage low or high.
Difference between actual throttle opening and open-
ing calculated by ECM in larger than specified value.
• TP sensor maladjusted.
• TP sensor circuit open or short.
• TP sensor malfunction.
• ECM malfunction.

without the above range.
Turn the ignition switch OFF.
Check the TP sensor coupler for loose or poor contacts.
If OK, then measure the TP sensor input voltage.
Disconnect the TP sensor/injector coupler 1 .
Turn the ignition switch ON.
Measure the voltage at the Red wire and ground.
If OK, then measure the voltage at the Red wire and B/Br
wire.
• Remove the fuel tank and air cleaner box. ( : 4-52 and -60)

Loose or poor contacts on
the ECM coupler.
Open or short circuit in the
Red wire or B/Br wire.
Turn the ignition switch OFF.
Disconnect the TP sensor/injector coupler.
Check the continuity between P/W wire and ground.
; TP sensor continuity: ∞Ω (Infinity)
(P/W – Ground)
If OK, then measure the TP sensor resistance at the
coupler (between P/W and B/Br wires).
Turn the throttle grip and measure the resistance.
