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 MAP Sensor Too High or Too Low
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 engine switch turned from off to on (IG) (starter remains off) | After the engine switch is turned on (IG), the difference between the atmospheric pressure sensor output and manifold absolute pressure sensor output is more than 8 kPa for 0.5 seconds (2 trip detection logic). | ECM |

INSPECTION PROCEDURE
- NOTICE:
- HINT:
1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0069) |
Connect the GTS to the DLC3.
Turn the engine switch on (IG) and turn the GTS on.
Enter the following menus: Engine and ECT / Trouble Codes.
Read the DTCs.
Result | Proceed to |
DTC P0069 is output | A |
DTC 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 GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Engine and ECT / 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 GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Clear the DTC ().
Turn the engine switch off and wait for 30 seconds or more.
Turn the engine switch on (IG) for 1 second.
Enter the following menus: Engine and ECT / Trouble Codes.
Confirm that the DTC is not output again.
