No Throttle Van: SureTrack Community Fix

December 14, 2021 by Nick Taylor

Read on to see how SureTrack can help you correct issues that are not easily diagnosed using OEM information alone. SureTrack is available at no additional cost in our ProDemand product.

Mechanics hate it when they fix a vehicle for one problem and a new unrelated one shows up. SureTrack community member SpidellChris had a Ford Econoline in their shop that they replaced the transmission and fuel tank and after putting it back together had a throttle issue. They posed the question to the community, and with the help of fellow community member Ericsautomotive and others, they were able to resolve the issue quickly.

The following Community Fix summarizes the interaction between members of the community that led to the solution.

Vehicle
2008 Ford Econoline E250 4.6L

Title
No Throttle response, check engine light on, corrected bad connection.

Complaint
Check engine light on, no throttle response.

Diagnostic Steps Performed/Parts Replaced
Vehicle was just in the shop for transmission replacement and fuel tank replacement. After putting it all back together check engine light came on and had thrown some codes. P2100 – Throttle Actuator Control (TAC) Motor Circuit/Open, P2104 – Throttle Actuator Control (TAC) System – Forced Idle, P2107 – Throttle Actuator Control (TAC) Module Processor, and P2110 – Throttle Actuator Control (TAC) System – Forced Limited RPM. So I cleared codes and reset KAM and they instantly returned. I replaced the throttle body and again cleared codes and reset KAM, performed test drive and vehicle ran great so I returned it to the customer. Vehicle was just towed back and codes P2100, P2104, P2107, P2110, P2111, and P2112 are set and there is no throttle response. What is going on, a defective Throttle Body? Any help would be appreciated.

Best Answer from Community Member Ericsautomotive
A loose T/Body connection has drove me crazy on one of these engines. If it checks good, the PCM might be at fault here.

Cause
Found connector on throttle body not making good connection.

Correction
Unplugged connector from throttle body and plugged back in and made sure it was fully seated and haven’t had an issue since.
