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.

GENERAL DESCRIPTION
BB:DTC P0172 SYSTEM TOO RICH (BANK 1)
1. OUTLINE OF DIAGNOSIS
Detect fuel system malfunction by the amount of main feedback control.
Diagnostic method
Fuel system is diagnosed by comparing the target air fuel ratio calculated by ECM with the actual air fuel ra-
tio measured by sensor.
2. ENABLE CONDITIONS
3. GENERAL DRIVING CYCLE
Perform the diagnosis continuously at idling or at a constant speed after warming up the engine.
4. DIAGNOSTIC METHOD
Abnormality Judgment
Compare the diagnosed value (fsobd) with the threshold value, and if a condition where the malfunction cri-
teria are met continues for more than 50 seconds, judge that there is a fault in the fuel system.
Time Needed for Diagnosis: 10 seconds × 5 times
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Normality Judgment
Judge as OK when the malfunction criteria below continues for 10 seconds.
5. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed

Map 2
Add the following value every 512 milliseconds.
4. GENERAL DRIVING CYCLE
Perform the diagnosis only once at a constant 70 km/h (43 MPH) or higher.
5. DIAGNOSTIC METHOD
After the execution criteria are established, calculate the output fluctuation value of front oxygen (A/F) sensor
(averaged for the right and left) and output fluctuation value of rear oxygen sensor. Calculate the diagnosis
value when the front oxygen (A/F) sensor output fluctuation value is more than specified value. A/F response
properties and diagnosis values are parameters for the judgment value.
Judge as NG when the malfunction criteria below are met. Judge as OK if the criteria below are not met.
Time Needed for Diagnosis: 30 to 55 seconds

cles.
