DTC detecting condition | Trouble area |
---|---|
Too long low signal of pulse signal from ECM to TCM continues out of specification. |
•
Throttle position sensor or its circuit malfunction.
• Throttle position signal circuit from ECM to TCM open or shorted to power circuit. • TCM • ECM |

1 |
Was
A/T System Check
performed?
|
Go to Step 2.
|
Go to
A/T System Check
.
|
2 |
Is there DTC related to throttle position sensor (P0120)?
|
Go to corresponding
DTC Table:M13A without VVT
.
|
Go to Step 3.
|
3 |
Check Throttle Position Signal Circuit for IG Short
1)
Turn ignition switch OFF.
2)
Disconnect TCM and ECM connectors from TCM and ECM.
3)
Check proper connection to TCM at terminal “E124-6” and to ECM at terminal “E113-15”.
4)
If OK, turn ignition switch ON and measure voltage between terminal “E124-6” of disconnected harness side TCM connector and ground.
Is it 10 – 14 V?
|
“BLK/RED” circuit shorted to power circuit.
|
Go to Step 4.
|
4 |
Check Throttle Position Signal Circuit for Open
1)
Turn ignition switch OFF.
2)
Check continuity between terminal “E124-6” of disconnected harness side TCM connector and terminal “E113-15” of disconnected harness side ECM connector.
Is continuity indicated?
|
Intermittent trouble or faulty TCM or ECM. Check for intermittent referring to
Intermittent and Poor Connection Inspection
. If OK, substitute a known-good TCM or ECM and recheck.
|
“BLK/RED” circuit open.
