X22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

EEPROM

EEPROM

The Electronically Erasable Programmable Read Only
Memory (EEPROM) is a permanent memory that is
physically soldered within the ECM.  The EEPROM
contains program and calibration information that the
ECM needs to control Powertrain operation.

901RX031

Functional Check

1. Perform the On–Board Diagnostic System Check.
2. Start the engine and run for least one minute.
3. Check for DTCs using Tech 2.
4. If the ECM fails to program, proceed as follow:

D

Ensure that all ECM connections are OK.

D

Check the ITCS for latest version software.

D

Attempt to program ECM again. If ECM still cannot
be programmed properly, replace ECM. The
replacement ECM must be programmed.

Engine Coolant Temperature

(ECT) Sensor

Removal Procedure

1. Disconnect the negative battery cable.
2. Drain enough engine coolant so that the coolant level

will be below the ECT sensor.

3. Remove electrical connector from the sensor located

on the intake manifold above the ignition coil.

4. Unscrew the sensor from the manifold.

014RX008

Installation Procedure

1. Install the sensor into the intake manifold. Do not over

tighten.

2. Connect electrical connector.

3. Add engine coolant to required level. Refer to Engine

Cooling System Section.

4. Connect the negative battery cable.

Heated Oxygen Sensor (HO2S)

Removal Procedure

1. Disconnect the negative battery cable.
2. Locate the two oxygen sensors.

D

Bank 1 sensor 1 is mounted on the exhaust pipe
ahead of the catalytic converter.

D

Bank 1 sensor 2 is mounted on the exhaust pipe
behind the catalytic converter.

3. Disconnect pig tail electrical connector.

IMPORTANT:

The pigtail is permanently attached to

the sensor. Be careful not to pull the wires out.

014RX010

4. Unscrew sensors form the exhaust pipe. Because of

the expansion and contraction of the metal in the
exhaust system over time, this may be difficult if the
engine temperature is below 48 degree C.

Inspection Procedure

NOTE: Both sensors are identical. Inspect each inthe
same way.

1. Inspect the pigtail and the electrical connector for

grease, dirt, corrosion and bare wire or worn
insulation.

2. Inspect the louvered end of the sensor for grease,

dirt, excessive carbon build up or other contaminants.

TS23739

Installation Procedure

NOTE: If HO2S is reinstalled after removal, special
anti–seize compound or the equivalent should be applied
to the threads. Special anti–seize compound, (P/N
5613695), is used on the HO2S threads. This compound
consists of glass beads suspended in a liquid graphite
solution. The graphite burns away with exhaust heat, but
the glass beads will remain, making the sensor easier to
remove.

X22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

1. Apply anti–seize compound or the equivalent to the

thread.

TS23739

2. Install HO2S on the exhaust pipe.
3. Tighten the sensor to 55 Nm (5.6 kg·m/40 lb ft)
4. Connect the pig tail to the wiring harness.
5. Connect the negative battery cable.

Intake Air Temperature (IAT)

Sensor

Removal Procedure

1. Disconnect the negative battery cable.
2. The IAT sensor is located in the intake air duct

between the air filter and the throttle body.

3. Disconnect the electrical connector from the sensor.
4. Remove the sensor from intake air duct by using a

rocking motion while pulling the sensor.

0018

Installation Procedure

1. Install the IAT sensor into intake air duct. Make sure

the sensoris pushed all the way into the intake air
duct.

2. Connect electrical connector.
3. Connect the negative battery cable.

014RX011

Manifold Absolute Pressure

(MAP) Sensor

Removal Procedure

1. Disconnect the negative battery cable.
2. Disconnect the electrical connector from the sensor.

(The MAP sensoris located on the intake manifold
behind throttle body.)

3. Remove a mounting bolt securing the sensor to the

manifold.

4. Remove the sensor from the intake manifold using

rocking motion while pulling the sensor.

014RX012

Installation Procedure

1. Push MAP sensor into the manifold. Make sure the

sensor is pushed always into its position.

2. Install a mounting bolts and tighten.
3. Connect electrical connector.
4. Connect the negative battery cable.
