Faulty signal. Intermittent fault
Check mass air flow (MAF) sensor connector for intermittent contact resistance and oxidation according to Contact resistance and oxidation .
Remedy as necessary.
Other information:
- To access/replace the Mass Air Flow (MAF) sensor, see Replacing the mass air flow (MAF) sensor .
- For information about signals, see Signal specification
- To connect the breakout box, see Connecting the breakout box
- To access the control module, see Engine control module (ECM), replacing
NOTE:
The manifold absolute pressure (MAP) sensor is integrated into the mass air flow (MAF) sensor and cannot be replaced separately.
