MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.0L>
13B-22
DIAGNOSTIC TROUBLE CODE CHART
M1131151000163
Knock sensor
Switches the ignition timing from ignition timing for high octane to ignition timing
for standard octane fuel.
Communication line with
transaxle control CPU
No ignition timing retard control (overall engine-transaxle control) achieved
when transaxle speeds are changed.
Generator FR terminal
Does not restrict the generator output with respect to electrical load.
Heated oxygen sensor
<front>
Air/fuel ratio closed loop control is not performed.
Heated oxygen sensor
<rear>
Performs the closed loop control of the air/fuel ratio by using only the signal of
the heated oxygen sensor (front) installed on the front side of the catalytic
converter.
Misfire detection
The ECM <M/T> or PCM <A/T> stops supplying fuel to the cylinder with the
highest misfiring rate if a misfiring that could damage the catalytic converter is
detected.
