What P2119 means
This is a mechanical performance check of the electronic throttle body. GM calls it Throttle Closed Position Performance: after the motor is de-energized the return springs must bring the plate into its default (limp) position, e.g. 1.32-1.90 V on TP sensor 1 in GM's 2006 tables; 15 failed samples in a row set it. A Bosch-based GM ECM times the spring return at key-on (fault above 0.56 s). Toyota, Lexus, Ford (Ranger/Bronco, ice behind the throttle) and Mitsubishi use the code too. Unlike P2101 (position error while driven) or P2118 (motor current), P2119 points at a sticking or iced plate or a weak spring; the engine may enter limp mode.
P2119 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2119
- Engine warning lamp on
- Reduced power or limp mode
- Hesitation or uneven acceleration
- Raised or unstable idle
Common causes of P2119
- Most likelyCarbon deposits make the throttle plate stick
- PossibleWater or ice in the intake behind the throttle body
- PossibleWeak return spring or worn gear in the throttle body
- Less likelyECM software that sets the code falsely (update available)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2119 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1 | Area: fuel and air metering. |
| 19 | The exact fault in that area. |
What to do next
- Note P2119 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2119
What does P2119 mean?
P2119 means "Throttle Actuator A Control Throttle Body Range/Performance". This is a mechanical performance check of the electronic throttle body. It is a generic code, so it means the same on every make.
Is it safe to drive with P2119?
Drive gently and only to a workshop. With P2119 the car can go into limp mode (reduced power) to protect itself.
Will P2119 fail an emissions test?
Yes, it can. P2119 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2119 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2119 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
