ENGINE GENERAL INFORMATION AND DIAGNOSIS (H27 ENGINE) 6-1-21
DETECTING CONDITION
(DTC will set when detecting : )
Difference between desired idle speed
and actual idle speed continues to
exceed specified value for longer than
specified time.
Data write error (or check sum error)
when written into ECM
Manifold absolute pressure sensor
output voltage is higher or lower than
specified value (or sensor circuit
shorted to ground or open).
Barometric pressure is lower or higher
than specification.
Difference between intake manifold
pressure and barometric pressure is
larger than specification.
Engine starts with no starter signal or
signal input during long period after
start.
No back-up power after starting
engine.
DETECTING CONDITION
(DTC will set when detecting : )
Multiple signals inputted simulta-
neously or P, R, N, D, 2 or L range sig-
nal not inputted while running at
60km/h or more.
Input speed sensor signal is lower
than specification while running.
Output speed sensor signal not input-
ted while VSS signal being inputted.
Actual TCC operation does not agree
with ON/OFF control from PCM to
TCC.
Monitor signal OFF is detected when
TCC control solenoid is ON or monitor
signal ON is detected when it is OFF.
Gear change control from PCM to A/T
does not agree with actual gear posi-
tion of A/T.
