P2119: Throttle Actuator A Control Throttle Body Range/Performance

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.

Symptoms

• Engine warning lamp on
• Reduced power or limp mode
• Hesitation or uneven acceleration
• Raised or unstable idle

Most likely causes

• Carbon deposits make the throttle plate stick
• Water or ice in the intake behind the throttle body
• Weak return spring or worn gear in the throttle body
• ECM software that sets the code falsely (update available)

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the pedal and throttle connectors
2. Compare the reading with other engine data while varying the engine speed.
3. Use live data to confirm that both sensors rise smoothly and consistently
4. Clean the throttle if it has carbon buildup
5. Run the relearn procedure with the scanner if the manufacturer requires it
6. Replace the part identified by the diagnosis

Good to know

• Repair difficulty: medium
• It can trigger limp mode.
• It affects emissions.

What each character of P2119 means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• 1: Air and fuel
• 19: Specific fault in that system

Frequently asked questions

Can I keep driving with code P2119?

Be careful: the car may suddenly lose power. If it goes into limp mode, get off the highway and calmly make your way to a repair shop.

What causes code P2119?

The most common causes are: carbon deposits make the throttle plate stick; water or ice in the intake behind the throttle body; weak return spring or worn gear in the throttle body.
