hey guys my truck has the codes P0122, P01151, P01152 and, P0174. My truck runs ruff when you put it into drive and sometimes when i stop at a light, it will also suddenly drop about 500 RPMs and then jump back up to normal. If you guys have any ideas please let me know.

 

Are you still leaking oil and coolant from the side somewhere? If so, that info should be included here.

 

yea a lit still leaks a little bit of oil

 

A P0122 code is the TPS (throttle position sensor) reporting too low a voltage. A bad TPS can cause all of the codes that you are seeing. The other codes are too lean and too rich. Check the output of your TPS and see what it is reporting. If it is too low the TPS is usually less than $50 and are not that difficult to change. Youtube has a few detailed videos and it is a strait forward replacement.

P0122 - low voltage reported by TPS
P01151 - Ford Specific: A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition
P01152 - Ford Specific: Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2
P0174 - System Too Lean (Bank 2)

You can find all of the codes at www.obd-codes.com

 

Yes, +1^^^ do as Tsquare suggests

Test or replace TPS
And reset/erase the codes so Computer can relearn TPS settings
