Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 1VD-FTV ENGINE CONTROL
CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0069)
INSPECT MANIFOLD ABSOLUTE PRESSURE SENSOR
CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED
DTC P0069 Manifold Absolute Pressure - Barometric Pressure Correlation
DESCRIPTION
To detect atmospheric pressure, the atmospheric pressure sensor built into the ECM is used in the common rail system. Following the changes in the atmospheric pressure, the ECM corrects the fuel injection volume, timing and duration, and adjusts the common rail internal fuel pressure to optimize combustion.
DTC Detection Drive Pattern | DTC Detection Condition | Trouble Area |
1 second elapses after ignition switch turned from off to ON (starter remains off) | After the ignition switch is turned to ON, the difference between the atmospheric pressure sensor output and manifold absolute pressure sensor output exceeds the range of +/-8 kPa for 0.5 seconds. | Manifold absolute pressure sensor ECM |

INSPECTION PROCEDURE
- NOTICE:
- After replacing the ECM, the new ECM needs registration () and initialization ().
- HINT:
1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0069) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the tester on.
Enter the following menus: Powertrain / Engine / DTC.
Read the DTCs.
Result | Proceed to |
P0069 is output | A |
P0069 and other DTCs are output | B |
- HINT:
- If codes other than P0069 are output, perform troubleshooting for those DTCs first.

A | |
2.INSPECT MANIFOLD ABSOLUTE PRESSURE SENSOR |
- HINT:
- Before inspecting the manifold absolute pressure sensor, perform a wire harness inspection and if there are any problems with the wire harness, repair or replace it.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine / Data List / MAP.
Read the value.
- OK:
- Same value as the actual atmospheric pressure.
|
| ||||
OK | |
3.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED |
Connect the intelligent tester to the DLC3.
Clear the DTC ().
Turn the ignition switch off.
Turn the ignition switch to ON for 1 second.
Enter the following menus: Powertrain / Engine / DTC.
Read the DTCs.
Result | Proceed to |
P0069 is output | A |
No DTC is output | B |
