Applicable Systems
OBD-II
Symptoms
The sensor signal is outside the expected range or performance is below specification.
Possible Causes
- Sensor reading out of calibrated range due to wear or contamination
- Mechanical component affecting sensor performance
- Wiring resistance high causing signal degradation
Troubleshooting Steps
- Step 1: Compare sensor reading with expected value at current conditions
Reading deviates from expected - Step 2: Inspect related mechanical components for wear
Mechanical issue identified - Step 3: Check wiring for high resistance or corrosion
Wiring resistance normal
How to Reset
