P2106Throttle Actuator Control System - Forced Limited Power
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2106 tells you the throttle control is running in a reduced-power fallback. Ford's 2012 summary lists the reasons on second-generation ETC: loss of the MAF signal, one throttle position sensor, crank position or transmission speed sensors, a stuck throttle or a throttle motor circuit fault; it sets with MIL and wrench lamp, and a crank sensor code (P0320/P0322) also adds P2106. VW's 2014 data book uses it when an internal plausibility check of the engine computer fails. So P2106 almost always appears with another code that names the real defect, and that one is repaired first. The driver notices weak acceleration and a capped top speed. Forced idle is P2104, limited rpm P2110, shutdown P2105.
- What you may notice
- Reduced power, sluggish acceleration
- Engine and wrench/ETC lamp on
- Limited road speed
- Likely causes
- LikelyFailed input such as MAF, throttle position or crank sensor
- PossibleSticking throttle or fault in the throttle motor circuit
- RareFailed internal check or software in the engine computer
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
