i got this code and ckf but i believe i fixed the ckf by hacking the ecu..anyhow, this P0141 isnt a o2 replacement (searched) but wire malfunction...(i think)question is where? is there a tool to diagnose this? running p75 ecu obd2a if that helps.

 

p0141 is usually caused by an open o2 sensor heater. A resistance check of the secondary o2 heater will verify it's the problem.

 

should i have car running when its being tested? how do i set my meter? what # is it suppose to show? google didnt help much... im a n00b at this

Doesn't need to be running. disconnect the sensor. Measure resistance between the two black wires on the sensor. Use the ohms setting, should be 10-40 ohms if I remember right.

 

checked and 2nd o2 is fine ... new ecu maybe?

A problem with a wire, connector, or pin would be my next suggestions to check. Do you have power and/or ground to the o2 heater?

 

ground? isnt one of the black wire, ground?

going to check what you mentioned. pain in the ****! =\

 

i know im bringing post from the dead but i was wondering if you ever fixed it?

 

useally the heaters go out wit o2 sensors my experiance is just to change it

 

yeah, changed both o2 sensors today, and now its throwing p0135 code and p0141... o2 sensors are good, checked, tomorow picking up ecu... i need to pass emissions in 2 days... any help is apreciated, btw sorry op for stealing your thread lol
