TP Sensor Signal check:
(1) Remove ECM (PCM) cover.
(2) Start engine and warm up for normal operating
temperature then stop engine.
(3) With ignition switch ON leaving engine stop, check
voltage between C51-3-12 and C51-3-20.
Fully close: 0.35 – 0.65 V
Fully open: 3.5 – 4.5 V
Is check result as specified?
Go to Step 3.
Go to Step 4.
3
Air Intake System inspection:
(1) Check air intake system for clog and air inhabit.
Is air intake system in good condition?
Substitute a known-
good ECM (PCM)
and recheck.
Repair or replace.
4
TP Sensor Performance check:
(1) Check TP sensor referring to “ENGINE AND
EMISSION CONTROL” section.
Is check result as specified?
Go to Step 5.
Faulty TP sensor.
5
TP Sensor Reference Voltage check:
(1) With ignition switch OFF, disconnect TP sensor
coupler (C30).
(2) With ignition switch ON, check voltage between
C30-3 and ground.
Is the voltage 4.5 – 5.5 V?
Go to Step 6.
Faulty “Gr / R” wire.
If OK, substitute a
known-good ECM
(PCM) and recheck.
6
TP Sensor Ground Circuit check:
(1) Check continuity between C30-1 and ground.
Is continuity in good condition?
Go to Step 7.
Faulty “Gr / Y” wire.
If OK, substitute a
known-good ECM
(PCM) and recheck.
7
TP Sensor Installation check:
(1) Check TP sensor installation referring to
“ENGINE AND EMISSION CONTROL” section.
Is TP sensor installation as specified?
Substitute a known-
good ECM (PCM)
and recheck.
