Customer Question

Customer: ***** *****, I have not checked with a DVOM yet but did however check that the throttle opened with key on engine off while pressing the accelarator & it did move. Therefore the plate is not stuck, what else might be causing this?
JA: Thanks. Can you give me any more details about your issue?
Customer: I hit a pot hole hard the car drove for another 2 blocks & shut down, it cranks & all but does not turn on. I hooked up my little scanner & retrieved codes P2104 & P2112.

Hello and welcome to JustAnswer!

These are indeed electronic throttle control codes and most likely point to a physical issue with the throttle body.

What is the year and model of the vehicle and what engine do you have?

Customer: replied 1 year ago.
2005 Lincoln LS V6 3.0
Expert:  sprinkles08 replied 1 year ago.

P2104 sets when the engine controller is forced to idle the engine due to n electronic throttle control issue, P2112 sets when the throttle angle is less than the commanded angle. This could be an internal issue in the engine controller but is almost surely a throttle body issue. If nothing foreign was in the throttle body blocking throttle blade movement at the time the code set then the throttle body should be replaced.

Customer: replied 1 year ago.
Prior to ordering the throttle body, from your expert opinion what percentage do you assume is the throttle body? I originally stated I hit a pothole hard, then drove for another 2 blocks & stalled not starting up again. I mean to me it's weird that the hit/bang would affect the throttle body know what I mean?
Expert:  sprinkles08 replied 1 year ago.

The problem may or may not have been related to hitting a pothole. There is a 99% chance that the problem is the throttle body or something foreign was blocking blade movement.

Customer: replied 1 year ago.
Nothing foreign is or was blocking the throttle plate. Do this cars have a gas cut off switch that may have moved with the hit/bang when the pothole was hit?
Expert:  sprinkles08 replied 1 year ago.

There is no inertia switch used, and if an inertia switch had tripped it would have had to be manually reset before the engine would start.

Customer: replied 1 year ago.
this car model does not have an inertia switch? I want to be certain before buying the throttle body because it's an expensive piece.
Expert:  sprinkles08 replied 1 year ago.

You do not have an inertia switch and if it did that wouldn't be related to an electronic throttle control issue.

Customer: replied 1 year ago.
I have the green light to replace the throttle body is what you're saying?
Expert:  sprinkles08 replied 1 year ago.

Yes, the problem is either the throttle body or something was physically blocking the blade from moving.
