X22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

Engine Control Module (ECM)

Electrostatic Discharge (ESD) 
Damage

Electronic components used in the control system are
often designed to carry very low voltage. Electronic
components are susceptible to damage caused by
electrostatic discharge. Less than 100 volts of static
electricity can cause damage to same electronic
components. By comparison, it takes as much as 4000
volts for a person to even feel the zap of a static
discharge. There are several way for a person to become
statically charged. The most common methods of
charging are by friction and by induction. An example of
charging by friction is a person sliding across a car seat.
Charging by induction occurs when a person with well
insulated shoes stands near a highly charged object and
momentarily touches ground. Charge of the same polarity
are drained off leaving the person highly charged with
opposite  polarity. Static charge can cause damage,
therefore, it is important to use care when handling and
testing electronic components.

NOTE: To prevent possible Electrostatic Discharge
damage, follow these guidelines:

D

Do not touch the control module connector pins or
soldered components on the control module circuit
board.

D

Do not open the replacement part package until the
part is ready to be installed.

D

Before removing the parts from the package, ground
the package to a known good ground on the vehicle.

D

If the parts been handled while sliding across the
seat, or while sitting from standing position, or walking
a distance, touch a known good ground before
installing the parts.

NOTE: To prevent internal ECM damage, the ignition
must be OFF position in order to disconnect or reconnect
power to the ECM (for example: battery cable. pig tail,
ECM fuse, jumper cable, etc.).

IMPORTANT:

When replacing the production ECM

with a service ECM, it is important to transfer the
broadcast code and production ECM number to the
service ECM label. This will allow positive identification of
ECM parts throughout the service life of the vehicle.  Do
not record this information on ECM metal cover.

Removal Procedure

1. Disconnect the negative battery cable.
2. Block the wheels.
3. Remove ashtray inner.
4. Remove a screw located behind ashtray.

Throttle Position (TP) Sensor

Removal Procedure

1. Disconnect the negative battery cable.
2. Disconnect the TPS electrical connector.
3. Remove the two screws and TP sensor from the

throttle body.

NOTE: Do not clean the TP sensor by soaking it in
solvent. The sensor will be damaged as a result.

X22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

Function Check

Use a Tech 2 to check the TP sensor output voltage at
closed throttle.

D

The voltage should be under 0.25 volts.

D

If the reading is greater than 0.25 volts, check the
throttle shaft to see if it is binding. Check that the
throttle cable is properly adjusted, also. Refer to
Throttle Cable Adjustment. 

D

If the throttle shaft is not binding and the throttle cable
is properly adjusted, install a new TP sensor.

101RX003

Installation Procedure

1. Install the TP sensor on the throttle body with two

screws.

2. Connect the electrical connector.

3. Connect the negative battery cable.

Vehicle Speed Sensor (VSS)

Removal Procedure

1. Disconnect the negative battery cable.
2. VSS is located on the right side of the transmission

case just ahead of the rear propeller shaft.
Disconnect the VSS electrical connector.

3. Remove the bolt and the VSS from the transmission

case by wiggling it slightly and pulling it straight out.

IMPORTANT:

Have a container ready to catch any fluid

that leaks out when the VSS is removed from the transfer
case.
