could someone show me or tell me where the Primary oxygen sensor heater is located please?

 

The one on the header in the front. The heater is a part of the sensor.

 

the other guy said where it is but that may not be the issue. have you dont any mods recently?

 

basically your car sees that the power circuit going to the o2 sensor is not correct. bad ground no power or whatever. first check to make sure that the o2 wires are not pinched broke cut torn or disconected. if there isn o problem check even closer to the ecu in the wire harness. If it continues just replace the the o2 sensor.

 

okay, ill check all of that in the morning, i bet that one of the wires came out of the plug
