Code P170
 

i got a car with a check engline light on, i went to my buddy's place to check out what was the problem. he said that the check engine light was giving him code P170, later on i found out that my air intake tube was cracked, so i patched it up as good as i could and my buddy turned off the check engine light. it didnt come back for a couple of days, so i thought i needed a new tube, but the next day when i went for a drive i found that the check engine light went off. couple days later and went on again, and then off again, and it just keeps on doing it. this morning i started the car with the engine light on and after i came back to the car i found it to be on again. i just don't know what could be the problem, code P170 is for the fuel trim, if anyone knows what could be causing it, please let me know. thanks

fixed that some time ago now, but i scanned today again and found out that it was a knock sensor that made my check engine light go on and off. thanks anyway keninn!

huh? one scan is p0170(fuel trim, right bank), another scan is 0325(knock sensor)? either you got 2 codes, or someone dont know how to use a scan tool. also, the leak in the intake would not throw a code for only 1 bank, since both sides would be affected.

i got code P170 when i just got my car, and then i found that the tube was cracked, so i patched it up for the time being, and it went off, and then check engine light started going on and off, so i scanned today again to see if it's still the same code, and it gave me code P1325 i believe. i just thought it was the same code all along
