P2110: Throttle Actuator A Control System - Forced Limited RPM
A generic powertrain (engine and transmission) trouble code, same meaning on every brand.
Yes, within the RPM ceiling it sets - fine for surface streets, marginal for highway on-ramps.
Symptoms
- Engine refuses to rev past a set point
- Reduced power warning
- Normal behavior below the cap
- Companion throttle or pedal codes
Likely causes, most common first
- Throttle actuator fault judged moderate by the computer
- Pedal or throttle sensor disagreement
- Intermittent wiring fault
- Root cause named by companion codes
Read P2110 yourself before paying for diagnosis
A basic Bluetooth OBD-II scanner ($20-40) plugs into the port under the dashboard and shows this code with live sensor data on your phone - useful both for confirming the fix and for talking to a shop from an informed position.
What is going on and how it gets diagnosed
P2110 records that the throttle system limited maximum engine speed - a middle rung on the intervention ladder between full power and forced idle. The computer picks the rung by how badly the throttle data disagrees with expectations, so the same underlying fault can produce P2106 one day and P2110 the next as it worsens.
The road map is the same as for the whole family: pull all codes, chase the one that names hardware, fix that, then clear the set together. An intermittent version - power limited one trip, normal the next - points strongly at wiring or connectors rather than a dead part, and wiggle-testing the throttle and pedal connectors while watching live data often finds it faster than any parts swap.
Repair options and cost
Typical US independent-shop ranges, parts and labor. Dealers run higher; regional labor rates vary.

“My 08 forenza hesitates during cold start up. No codes show. It has 58000 miles (timing belt due in a few thousand), 5 speed stick , driven 90 miles one way every 3 third day. It did die on the highway back in january '11 , cel came on, went into limp mode,I didn't shut down for fear of completely dying it was towed to dealer. Pulled codes p2106, p2110, and p0835 from computer. Dealer found nothing wrong other than codes. Since then hesitation has been getting worse. It doesn't seem to idle normally all that well even after driving for several hours (seems like tps is sticking runs around 2000 for about 15 seconds after coming to a stop). *tr”2008 Suzuki Forenza · Jan 2011 · 53,714 mi
