I have an 06 saleen and the check engine came on so I checked the code with my scanner and it rea P0171 anyone out have the ability to tell me what this is? ( I am assuming an 02 sensor or something small)

thanks

 

A P0171 lean code for bank 1 is the cylinder bank on the RIGHT (passenger) side of the engine on Ford vehicles with a V6 or V8 engine and rear-wheel drive

Thats what i think could be wrong.


Trouble shooting: One of the most common causes of Ford P0171 and P0174 lean codes is a dirty mass airflow (MAF) sensor. The MAF sensor is located in the air inlet tube
just ahead of the throttle body.




























VACUUM LEAKS
Another common cause of Ford P0171 and P0174 ean codes is an engine vacuum leak. Ford TSB 04-17-4 details procedures for checking fuel trim and looking for vacuum leaks.

can be another cause
