STEP 16. Replace the injector.
(1) Replace the injector.
(2) Carry out a test drive with the drive cycle pattern. Refer to
GROUP 13A, Procedure 6
− Other Monitor
(3) Read in the diagnostic trouble code (DTC).
Q: Is DTC P0201, P0202, P0203, P0204, P0205 and P0206
set?
YES : Replace the PCM. Then go to Step 17.
NO : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points
STEP 17. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to
GROUP 13A, Procedure 6
− Other Monitor
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0201, P0202, P0203, P0204, P0205 and P0206

DIAGNOSTIC TROUBLE CODE PROCEDURES
13Ac-330
P0222 Throttle Position Sensor (Sub) Circuit Low Input
.
CIRCUIT OPERATION
• A 5-volt power supply is applied on the TPS (sub)
power terminal (terminal No. 2) from the PCM
(terminal No. 106).
The ground terminal (terminal No. 4) is grounded
with PCM (terminal No. 105).
• When the throttle valve shaft is turned from the
idle position to the fully opened position, the
resister between the TPS (sub) output terminal
(terminal No. 3) and ground terminal will increase
according to the rotation.

DIAGNOSTIC TROUBLE CODE PROCEDURES
13Ac-331
TECHNICAL DESCRIPTION
• The TPS (sub) outputs voltage which corre-
sponds to the throttle valve opening angle.
• The PCM checks whether the voltage is within a
specified range.
.
DTC SET CONDITIONS
Check Conditions
• Ignition switch "ON" position.
Judgement Criteria
• TPS (main) output voltage should be 2.25 volts or
more for 0.5 seconds.
.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)
• TPS failed or maladjusted.
• Open or shorted TPS (sub) circuit, or loose con-
nector.
• PCM failed.
DIAGNOSIS
Required Special Tool:
• MB991502: Scan Tool (MUT-II)
STEP 1. Using scan tool MB991502, check data list item 14:
Throttle Position Sensor (sub).
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK"(OFF) position before con-
necting 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) Detach the intake air hose at the throttle body.
(4) Disconnect the connector of the throttle position sensor.
(5) Use test harness special tool (MB991348) to connect only
terminals No. 1, No. 2, No. 3, and No. 4.
(6) Set scan tool MB991502 to the data reading mode for item
14, Throttle Position Sensor (sub).
• Output voltage should be between 2.2 and 2.8 volts
when the throttle valve is fully closed with your finger.
• Output voltage should be between 3.8 and 4.9 volts
when the throttle valve is fully open with your finger.
(7) Turn the ignition switch to the "LOCK"(OFF) position.
Q: Is the sensor operating properly?
YES : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points
NO : Go to Step 2.
STEP 2. Check connector B-05 at throttle position sensor
for damage.
Q: Is the connector in good condition?
YES : Go to Step 3.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 12.

STEP 3. Measure the sensor supply voltage at throttle
position sensor harness side connector B-05.
(1) Disconnect the connector B-05 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 2 and ground
• Voltage should be between 4.8 and 5.2 volts.
(4) Turn the ignition switch to the "LOCK"(OFF) position.
Q: Is the measured voltage between 4.8 and 5.2 volts?
YES : Go to Step 7.
NO : Go to Step 4.
STEP 4. Check connector D-135 at PCM for damage.
Q: Is the connector in good condition?
YES : Go to Step 5.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 12.
