Diagnostic Trouble Code (DTC) Detecting Criteria
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.
2. COMPONENT DESCRIPTION
3. ENABLE CONDITIONS
4. GENERAL DRIVING CYCLE
Perform the diagnosis continuously after idling.
5. DIAGNOSTIC METHOD
Abnormality Judgment
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.
(A) Output voltage (B) Absolute pressure

GENERAL DESCRIPTION
Time Needed for Diagnosis:
3 seconds (Low side)
10 seconds (High side)
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Normality Judgment
Judge as OK and clear the NG when both Low side and High side become OK.
Judge as OK when the malfunction criteria below are completed.
6. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed
7. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
•When the OK driving cycle is completed 3 times in a row
•When “Clear Memory” is performed
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
