GENERAL DESCRIPTION
EM:DTC P2227 BAROMETRIC PRESSURE CIRCUIT RANGE/ PERFORMANCE
1. OUTLINE OF DIAGNOSIS
Detect the malfunction of atmospheric pressure sensor output property.
Judge as NG when the atmospheric pressure sensor output is largely different from the intake manifold pres-
sure at engine starting.
2. COMPONENT DESCRIPTION
The barometric pressure sensor is built into the ECM.
3. ENABLE CONDITIONS
4. GENERAL DRIVING CYCLE
Perform the diagnosis once at ignition switch ON.
5. DIAGNOSTIC METHOD
Abnormality Judgment
Judge as NG when the continuous time until completing the malfunction criteria below becomes 0.3 second
or more.
Time Needed for Diagnosis: 0.3 second
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Normality Judgment
Judge as OK and clear the NG when the continuous time of completing the malfunction criteria below be-
comes more than 0.262 second.
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
Atmospheric pressure sensor process: Atmospheric pressure fixed at 101 kPa (760 mmHg, 29.8 inHg).
9. ECM OPERATION AT DTC SETTING
