Circuit description
Refer to dtc p0130
Hint:
the ecm provides a pulse width modulated control circuit to adjust current
through the heater. The heated
oxygen sensor heater circuit uses a relay on the b+ side of the circuit.
Monitor description
The ecm uses the heated oxygen sensor information to regulate t ...
Inspection procedure
1 Check connector
Disconnect the negative (–) terminal cable from the battery, and wait at
least for 90 seconds.
check the connection of the combination meter connector and the
airbag sensor assy center connectors.
Ok:
the connectors are connected.
2 Check combination ...
