96 Accord Ex 2.2 vtec auto

Last week my engine light came on I pulled the codes with a code reader and got a 0171 - which it to lean in bank 1. I replaced the first o2 sensor and reset the light. 2 days later the light is back on and I pull the codes again, same thing . The car seems to be running fine no hesitation or rough idle. Don't know what I should be checking next any help would be great.

 

Ideas anyone?

 

Do you mean 2 codes my code pages say 1 is your o2 sensor &code 71 is cylinder 1 misfire or random misfire a condition is present that is creating a cylinder misfire no code0171

"System too lean"

 

OBD 2 where did you get that site from I stand corrected

 

Look at the sticky thread at top of Integra BB. Generally, the codes are the same across all Hondas beginning with '96. Some codes don't exist for Integra, for example those engines don't have EGR.

I got MY list from my Helm book for '98/'99 Accord. It's got not only the list, but detailed procedures for each code. It doesn't cover '96 so that's why I didn't get into details about what to check out.

 

Check fuel pressure. If pressure is too low, check pump, fuel feed pipe, filter and pressure regulator. If pressure is too high, check fuel pressure regulator and fuel return line. If pressure is fine, use vacuum pump and apply vacuum to EVAP purge control solenoid valve. If it holds vacuum check map sensor with your scan tool. If atmospheric pressure is not indicated on your scan tool, replace the map. If there is a reading, it should be 11.8in. Hg or less within 1 second after starting the car, if it isn't replace map sensor. If it does indicate 11.8in Hg within 1 sec after starting the car check valve clearance and EGR system. If valve clearance and EGR are ok, replace fuel injectors.

Good luck.
