3 monitors not ready
Hey guys, i got a quick question. I own a 2001 Hyundai Sonata 4cyl with 180,000 miles.
I have 3 monitors in not ready mode:
I got a check engine line code for p0171, bank 1 system too lean. I think i've fixed the issue, which could've been a dirty MAF, as i couldn't spot any leaks in the air intake. What I'm asking is, how do I get these monitors in ready mode? Was it because the system was "Too Lean" that CAT & O2s failed to function? I don't think it's a bad sensor, as it'd throw the CEL on with a sensor that may be bad. Same with the CAT or EVAP. So should i do drive cycles after i fixed the p0171 code to see if the monitors will go back in ready mode? Thanks! |

Re: 3 monitors not ready
Codes need to be cleared after repairs are made. Then do a complete drive cycle and recheck.
