Great video thank you very detailed and easy to follow
I have a 98 dodge ram 1500 with 5.2. Pulls a po171 code lean bank one slow response. I have replaced every sensor , vacuum leaks,idle control valve, catalytic converter, gasket under throttle body. Mas sensor. Can undo battery put back on truck runs great for fifty miles engine light comes on idles up and down, gets 5 mpg and reads lean bank one code. There's nothing else to replace that I know of. Help. Short term fuel reads 32.5 long term 0.0.
I get it. So since mine is a 2.9L, I would only have B1S1 and B1S2 correct? I get a p1133 once in a while. What I truly learned here is that I need a way better reader! HaHa!
Hai my 2008 gmc Denali is throwing p1133 and p 1153, which are upstream oxygen sensors. I changed both sensors and getting the same above code again. Any suggestions? Thanks
Tha battery need to be desconect to replace the censors thanks
hi im have gmc yukon 2007 same code p1133 you recommend change the 2 sensor thanks for your help
Did you have to clear the code or it went away automatically?
I just changed the new upstream sensors but this code came out p01133 what could it be
Bank 1 sensor 1 you replaced ?
I do all the labor myself
Hoping to fix Asap
