1. DTC Descriptor:
DTC
P0030
Pre-Catalytic oxygen sensor heating control circuit open
DTC
P0031
Pre-Catalytic oxygen sensor heating control circuit short to ground
DTC
P0032
Pre-Catalytic oxygen sensor heating control circuit short to power supply
The Pre-Catalytic heated oxygen sensor (HO
2
S) is used for fuel control. The sensor compares the oxygen content in ambient air
with the oxygen content in exhaust flow. Each heated oxygen sensor has an internal heating element for sensor heating. ECM
controls the heated oxygen sensor heating control circuit. This makes the system enter into the closed-loop control mode earlier,
so that ECM can calculate Air-Fuel ratio earlier. ECM commands heater control module switched on or off, so that heated oxygen
sensor works within the specified working temperature range. Engine control module detects the temperature by Measure the heater
current.
The Pre-Catalytic heated oxygen sensor heating coil voltage is provided by The Main Relay, which is controlled by ECM. When the
ignition switch is turned to "ON" position, harness connector EN02 terminal No.1 voltage is provided by the battery. ECM controls
heater working time through ECM harness connector EN01 terminal No.6.
