Question
What diagnostic methods apply to ECU analog-to-digital converter (ADC) faults?
Answer
It verifies accurate conversion of analog sensor signals to digital data.
Explain
ADC faults cause incorrect sensor data interpretation. CHEPQ diagnostic tools send known analog signals to the ECU, monitor digital output, detect ADC offset, gain errors, or channel failures, and verify calibration. This ensures precise sensor data processing, preventing drivability issues.
