GENERAL DESCRIPTION
Q: DTC P0068 MAP/MAF - THROTTLE POSITION CORRELATION
1. OUTLINE OF DIAGNOSIS
Detect problems in the intake manifold pressure sensor output properties. Determining from the engine con-
dition, if the intake manifold pressure AD value is small even when operating conditions suggest it should be
large, or if the intake manifold pressure AD value is large even though the operating condition suggest it
should be small, this is judged as being NG.

4. GENERAL DRIVING CYCLE

Judge NG when either Low side or High side becomes NG.
Judge as NG when the continuous time until completing the malfunction criteria below becomes more than
the predetermined time.

8. FAIL SAFE
•Intake manifold pressure sensor process: Estimate the pressure from the engine RPM and size of the
throttle opening. When the throttle opening is also NG, fix at 101 kPa (760 mmHg, 29.8 inHg).
•ISC control: ISC feedback amount calculation prohibited
•Purge control: Not allowed to purge

teria are met continues for more than 50 seconds, judge that there is a fault in the fuel system.
