My air fuel ratio sensor has lit off my "SES" light since upgrading intake what should i do?
1-Replace the sensor and hope it doesnt go off again?
2-Get a fuel management system in hopes that the sensor will no longer go off once the air fuel ratio is correct?
3-Have the car tuned?

Any help greatly apprecieted!

check all the work and make sure maf and sensor are hooked up correctly.

then get a tune.

 

Thanks for the help. On that note Does anyone know of a good tuning place near northern california?

 

What are your mods besides the intake you upgraded?

 

Clean your MAF and clear the code. It should go away.

 

Only engine mod is the intake. But also have aeriated disc brakes and a Nismo short shifter. Thanks for the advice ill try cleaning/clearing it. You NorCal guys near Santa Cruz/San Jose area?

 

Cleaned MAF and cleared the MIL light 20 miles later light came back on.
ODBII gave code p1273 Air/Fuel Ratio sensor Bank 1...Should i just replace it?

 

When cleaning the MAF i noticed the housing had a chip out of it and had been patched up with some cement glue leaving the interior surface with 1/16"high of bumpy hard glue stuck to the inside, the patch job is a total of approximatly 1inch by 2inches and 1/16 inch high. could this be altering the MAF sensor reading and in return setting off my Air/Fuel ratio sensor??
