MAF Sensor Out of Self-Test Range
1990-1998 Mazda MPV 3.0L V6
Description
The MAF sensor reading is outside the expected range during the PCM self-test. The airflow value does not match expected parameters for the current engine operating conditions during diagnostic testing.
Symptoms
- Check Engine Light
- Poor idle quality
- Hesitation
- Poor fuel economy
- Black smoke from exhaust
Common Causes
- Dirty MAF sensor
- Vacuum leak after MAF sensor
- Restricted air filter
- Faulty MAF sensor
- Intake air leak between MAF and throttle body
Diagnostic Steps
- Check and replace air filter if dirty
- Inspect intake ductwork for leaks between MAF and throttle body
- Clean MAF sensor with approved cleaner
- Check for vacuum leaks with smoke test
- Compare MAF readings to specification at idle and 2500 RPM
Repair Notes
Clean or replace the MAF sensor and repair any intake air leaks.
