DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
MAP sensor power supply circuit check
1)With ignition “OFF”, disconnect MAP sensor connector.
2)Check for proper terminal connection to MAP sensor connector.
3)If connection is OK, set ignition “ON”.
4)Check that voltage between “A1” and “A3” is approx. 5 V.
Is check result OK?
|
Go to Step 4.
|
Go to Step 3.
|
| 3 |
MAP sensor ground circuit check
1)Check that voltage between “A1” and ground is approx. 5 V.
Is check result OK?
|
Repair “A3” circuit.
If this DTC is detected again, replace ECM and recheck DTC.
|
Check “A1” circuit.
If defective circuit is found, repair “A1” circuit.
If circuit is OK, replace ECM and recheck DTC.

MAP sensor signal circuit check
1)With ignition “OFF”, disconnect “C01” and “E01” connectors from ECM.
2)Check for proper terminal connection to “C01” and “E01” connectors.
3)If connections are OK, check the following points.
•Resistance of “A2” circuit: less than 1 Ω
•Resistance between “A2” circuit and ground: infinity •Voltage of “A2” circuit: approx. 0 V (When ignition is “ON”) Is check result OK?
|
Go to Step 5.
|
Repair or replace defective wiring harness.
|
| 5 |
MAP sensor check
1)Check MAP sensor.
Is check result OK?
|
Replace ECM and recheck DTC.
|
Replace MAP sensor.
