MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>
13B-391
STEP 1. Using scan tool MB991502, read the A/T
diagnostic trouble code (DTC).
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Check the A/T-DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the A/T-DTC is output?
YES : Refer to GROUP 23A, Automatic Transaxle
Diagnosis

Diagnostic Trouble Code Chart (
NO : If DTC P0760 is output again after the MFI-DTC has
been erased, replace the PCM. Then check that the
DTC P0760 does not reset.
DTC P0765: Shift Solenoid D Malfunction
TECHNICAL DESCRIPTION
•
When a malfunction of the shift solenoid D
(overdrive solenoid) is detected, the transaxle
control CPU inside the powertrain control module
(PCM) outputs a malfunction signal to the engine
control CPU in the PCM.
DTC SET CONDITIONS
Check Conditions, Judgment Criteria
•
Overdrive solenoid failure signal is input to the
engine control CPU from the transaxle control
CPU.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)
•
Overdrive solenoid failed.
•
Open or shorted second solenoid circuit, or loose
connector.
•
PCM failed.

DTC P1400: Manifold Differential Pressure Sensor Circuit Malfunction
CIRCUIT OPERATION
•
A 5-volt voltage is applied on the manifold
differential pressure sensor power terminal
(terminal 3) from the ECM (terminal 42) <M/T> or
PCM (terminal 46) <A/T>. The ground terminal
(terminal 2) is grounded with the ECM (terminal
49) <M/T> or PCM (terminal 57) <A/T>.
•
A voltage proportional to the pressure in the
intake manifold plenum is sent from the manifold
differential pressure sensor output terminal
(terminal 1) to the ECM (terminal 92) <M/T> or
PCM (terminal 91) <A/T>.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TECHNICAL DESCRIPTION
•
The manifold differential pressure sensor outputs
a voltage which corresponds to the negative
pressure in the intake manifold.
•
The ECM <M/T> or PCM <A/T> checks whether
the voltage output by manifold differential
pressure sensor is within a specified range.

the engine. Note that this is only if the engine
coolant temperature is less than 0
