will the tps sensor cause po301 and po171 codes?
 

Hey guys,

Will the tps sensor or the throttle body its self cause 301 and 171 codes? I am still getting these codes and have done everything i possibly can....

I will do what ever i can or need to do. If you need pics will do!!

Please help!!

Thanks in advance!!!!!:confused:

In a simple answer, no. The P0301 is for a misfire in cylinder number 1 and the P0171 is for lean condition on bank 1. Both problems are on the same bank of the engine, so cure the misfire first.
