FUNCTION
- The barometric pressure sensor converts the barometric pressure into a voltage signal and inputs the signal to the engine-A/T-ECU.
- In response to the signal, the engine-A/T-ECU. corrects the fuel injection amount, etc.
TROUBLE JUDGMENT
Check Conditions
- 2 seconds later after the ignition switch has been in "ON" position or the engine has started up.
- The battery voltage is 8 V or more.
Judgment Criteria
- The sensor output voltage is 4.5 V or more (Barometric pressure of above 114 kPa or equivalent) for 2 seconds.
- The sensor output voltage is 0.2 V or less (Barometric pressure of below 53 kPa or equivalent) for 2 seconds.
PROBABLE CAUSE
- Failed barometric pressure sensor
