p1168 Closed Loop Control (Bank 2) so wich sensor is this exactly?
p1065 ECM Power Supply Heater
p1051 A/F Sensor heater (Bank 2)
can someone please point me in the right direction on fixing these?? thanks
i have a utec and the stock ecm has a technosquare reflash. i only have the front 2 o2 sensors and am running test pipes. i was told that i shouldnt have any problems with not having the rear o2 sensors. Sam from GTM told me this during our tuning this past monday. he could not retune the car due to fuel trim code, he also stated what i posted above.

 

no one??

 

P1051 - Possible causes - Harness or connectors (The A/F sensor 1 heater circuit is open or shorted.) or Air fuel ratio (A/F) sensor 1 heater

P1065 - Possible causes - Harness or connectors [The ECM power supply (back-up) circuit is open or shorted.] or ECM

p1168 - Possible causes - Harness or connectors [The air fuel ratio (A/F) sensor 1 circuit is open or shorted.] or Air fuel ratio (A/F) sensor 1 or Air fuel ratio (A/F) sensor 1 heater

 

which is sensor 1

 

if my car runs fine what could be wrong with the ECM, i mean what does open or shorted mean

 

Sensor 1 is the first sensor and both codes are for the passenger side.

 

cool thanks, now i just need some help on the ECM code and what could cause that problem
