MB991910: Main Harness A

STEP 1. Check harness connector C-123 at accelerator
pedal position sensor and harness connector B-11 at ECM
for damage.

Q:Is the harness connector in good condition?

YES:

Go to Step 2.

NO:

Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection P.00E-2. Then go to Step 4.

STEP 2. Check for harness damage between accelerator
pedal position sensor connector C-123 and ECM connector
B-11.

Data link

connector

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958 to the data link connector.

(2)

Turn the ignition switch to the "ON" position.

(3)

Check the following items in the data list. Refer to Data List
Reference Table P.13Ab-837.

a
.

Item 11: Accelerator Pedal Position Sensor (main).

b
.

Item 12: Accelerator Pedal Position Sensor (sub).

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Are they operating properly?

YES:

Go to Step 4.

NO:

Repair or replace it. Then go to Step 4.

STEP 4. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

(1)

Turn the ignition switch to the "ON" position.

(2)

After the DTC has been deleted, read the DTC again.

(3)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is DTC P2138 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.

DTC P2195: Heated Oxygen Sensor Inactive (bank 1, sensor 1)

M11310100268USA0000010000

TECHNICAL DESCRIPTION

｠

The ECM effects air/fuel ratio feedback control in
accordance with the signals from the right bank
heater oxygen sensor (front).

｠

If the right bank heated oxygen sensor (front) has
deteriorated, corrections will be made by the right
bank heated oxygen sensor (rear).

｠

DTC P2195 becomes stored in memory if a failure
is detected in the right bank heated oxygen sensor
(front).

DESCRIPTIONS OF MONITOR METHODS

Right bank heated oxygen sensor (front) output
voltage does not cross lean/rich criteria (about 0.5
volt) within specified period.

MONITOR EXECUTION
