sounds like an O2 sensor?? CAT?

 

yep everything is all good. i always recheck my lugs after getting the car worked on. kinda OCD like that. Glad you were able to spot that issue before something bad happened.

 

Scary stuff

I nearly had an accident like that with my VW Bug... but that was due to my own fault and being rushed out after doing work. Yuck. At least I caught it in time

 

I had this happen when I was leaving a mechanics with my old car.

Always check the basics, is a very good habit.

 

P0141: Yeah just the heater circuit on your *secondary* O2. Heats up the O2 so you get a good reading when your car is cold, and there is now some problem with that heating part of the sensor. Nobody likes replacing O2s for this stupid reason.

The secondary sensor is the one on your cat, easily visible when underneath your car. Very common problem and will not put your car into limp mode, but the light staying on will keep you from knowing if there is anything else wrong in the future. In my experience as soon as the code is cleared, it will come right back, and not something that only triggers when the car is cold.

To fix it, test the two white wires for conductivity (ohm meter) to be sure and then replace the O2 sensor.

 

Thanks for the heads up. Gonna check mine right when I get home. Drove to Monterey after the rolling and didn't notice anything. Always good to double check tho.

About the torque wrench calibration: are u still able to use the same settings after they calibrate or do u have to, say, set to 100lb ft to get 80lb ft? Good to know this service is available.

Thanks guys. Good lookin out!

 

oh i already knew what it was hahaha. but thanks for the info!
mac was trying to test it but it wasn't giving an exact reading.. so we ended up just snapping the tip off and putting the broken o2 back on for the moment. ordered my o2 on monday so it should be here roughly friday or saturday.
