The Engine Control Module (ECM) monitors the voltage drop across the sensor and uses this signal to warn the driver and derate the engine to avoid engine damage if the signal is not within programmed limits.
Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A14.EB:32 is above normal value
Observable symptoms
1) None
Probable cause
1) Engine control module (ECM)
2) Short circuit to 5V, Signal wire
3) Short circuit to voltage supply, signal wire
