availability.
•
Is
any related Service information available?
Yes
Perform repair or diagnosis according to available repair
information.
• If vehicle is not repaired, go to next step.
No
Go to next step.
2
VERIFY CURRENT INPUT SIGNAL STATUS
-
IS CONCERN INTERMITTENT OR CONSTANT
• Turn ignition key to OFF.
• Connect NGS tester to DLC.
• Start engine.
• Access TURBINE PID using NGS tester.
— IG ON: 0 rpm
— Idle: W ithin 600—700 rpm (P, N position)
• Are TURBINE PID readings within
specifications?
Yes
Go to intermittent concern troubleshooting procedure.
(See F1-142 INTERMITTENT CONCERN.)
No
Go to next step.
3
INSPECT POOR CONNECTION OF
INPUT/TURBINE SPEED SENSOR
CONNECTOR
• Turn ignition key to OFF.
• Disconnect input/turbine speed sensor
connector.
• Check for poor connection (damaged/
pulled-out terminals, corrosion, etc.).
• Is connection okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminals, then go to
Step 9.
4
INSPECT INPUT/TURBINE SPEED SENSOR
RESISTANCE
• Measure resistance between input/turbine
speed sensor terminals (part-side).
• Is resistance w ithin
250—600
i
2
between
input/turbine speed sensor terminals
(part-side)?
(See K2-35 INPUT/TURBINE SPEED SENSOR
INSPECTION.)
Yes
Go to next step.
No
Replace input/turbine speed sensor, then go to Step 9.
(See K2-35 INPUT/TURBINE SPEED SENSOR
REMOVAL/INSTALLATION.)
5
INSPECT INPUT/TURBINE SPEED SENSOR
• Remove input/turbine speed sensor.
• Is there iron powder stuck on input/turbine
speed sensor?
(See K2-35 INPUT/TURBINE SPEED SENSOR
REMOVAL/INSTALLATION.)
Yes
Clean input/turbine speed sensor, then go to Step 9.
No
Go to next step.
6
INSPECT POOR CONNECTION OF PCM
CONNECTOR
• Disconnect PCM connector.
• Check for poor connection (damaged/
pulled-out terminals, corrosion, etc.).
• Is connection okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminals, then go to
Step 9.
7
INSPECT INPUT/TURBINE SPEED SENSOR
CIRCUIT FOR OPEN
• Inspect input/turbine speed sensor terminals
(harness-side) and PCM terminals
(hamess-side).
— A and 23
— B and 84
• Is there continuity?
Yes
Go to next step.
No
Repair or replace harness, then go to Step 9.
8
INSPECT INPUT/TURBINE SPEED SENSOR
CIRCUIT FOR SHORT TO GROUND
• Inspect input/turbine speed sensor terminal
(hamess-side) and body ground.
— A and body ground
— B and body ground
• Is there any continuity?
Yes
Repair or replace harness, then go to next step.
No
Go to next step.
