My son has been using my car for the past several weeks.
Today he texted me Check Engine light came on. :O
When he got home he used his 20$ scan tool to check codes.
And Yes it will go to my mechanic as I am auto tech challenged , And he will scan with a good OBD tool. lol
So I would like to know what these are ?

Thanks
I assume a O2 sensor

Codes arP0053
H02 Heater Resistance

PO135
o2 Sensor Heater circuit P0030
Heater Control Circuit

and B2aaa-unknown

Could be a burnt wire or blown fuse , or the O2 sensor has failed

 

B2aaa is a scanner code. It doesn't mean anything to you.
P0053 means high or low resistance in the #1 O2 sensor heater. Doubtful the fuse since both sensors use the same one. So, either the wire or the sensor.

 

THANKYOU I am just trying to understand more about my HHR . So all your help is great. :) Thank Yo0u.
I was 99.9% sure it was the o2 sensor again !
Both were replaced a year or so ago, so maybe the connection is bad ,Will see ,
Good thing I have a good mechanic .I can trust not to hose me. BUT good to know it is not a major issue !
If the Sensors are shot already I will ask him to get another brand maybe OEM, Does that make sense ?

 

Thanks for the links, I did see that earlier but good having better info from you guys !
The heated O2 sensor thing threw me off


THANKS

 

Thanks for the info on the B2aaa code and your help

 

What brand sensor was installed?

 

LOL That is a question I was going to ask him lol.And I was going to ask you guys what is the best one to use !
If he purchased from where I used to work May be STANARD.
I was thinking of him going OEM if they are better ! Or what is a better brand ?

 

OEM is a good choice

 

I wonder what is the difference between Upstream and Down Stream Sensors ?

If my mechanic used Standard Sensors I found out they have a 3 year warranty ! But I am willing to pay for a better brand and only do it once more lol

Thanks
