Hi Guys,
I've the some issue with my 2006 f150 lariat.
Before cleaning the throttle body i have faced the engine hesitation from 1800~2200rpm (NO reaction).
After having cleaned,
Engine start but no response at all on throttle pedal (but can hear that the clap inside of the throttle is activated several times "open ,closed very fast) .
Then Engine light pop up (safe mode activated, but cannot read the error code with my OBD).
Found some values as below:
Ohms between pin #4 & #14 --> 0 ohm instead of 60 Ohms
#16 --> 12 volts = ok
Can any body help?

Zero ohms is a short, so I'm wondering if you cleaned it with something that melted the varnish insulation off the internal components.

 

Hi,
Do you mean wash the engine compartment?
If So not at all.
The error codes reading was ok for 1~2 year and then suddenly could not anymore.

 

Is there any ways to check if it's really the case?

 

They are subject to failure . The gas pedal sends signal to pcm ,pcm sends coded signal to circuit board on motor on side of throttle body ,tps reports where throttle is at back to pcm ,any mismatch and it shuts down .
New throttle body for the revised model was running around $200 oem on ebay. Mine was replaced 100k ago by me seems there was a bad series of them around 05 . I tried a tps and cleaning but it kept failing . No amount of cleaning or testing is going to fix a bad one .

 

I'm gonna buy new body ***'y tomorrow from Ford to avoid any mistake.
Regarding Ohms on pin #6 and #14 i've got now 60ohms with batt disconnected !!! (strange)
But still cannot connect OBD tool in order to check the error code.
Thanks for your feedback.

 

Hi Red,
Issue solved by replacement of throttle body ***'y from Motorcraft $$$$$$$$$$
It look that the issue is well known from Ford, because mine was 6L3 type and they provide me 8L type
Thank again for your support
