Intake Temperature
Sensor
Intake temperature sensor signal error fluctuation
Check if the intake air temperature sensor is con-
nected effectively. If the error still persist ask for as-
sistance.
Intake Air Temperature
Sensor (IAT)
IAT Circuit High Voltage or Open
Intake Temperature
Sensor
Intake temperature sensor signal stuck
Check if there's history error. Reset. If the error still
persist ask for assistance.
Front oxygen sensor PE too thin
Check if the front oxygen sensor is connected effec-
tively. If the error still persist ask for assistance.
Front oxygen sensor too thick when fuel cutoff for
deceleration
O2S 1 Circuit High Voltage
O2S 1 Circuit Low Voltage
O2S Heater Circuit Low Voltage/Open Circuit
O2S Heater Circuit High Voltage
Check if the voltage regulator is connected effec-
tively. Reset. If the error still persist ask for assistance.
