What P2118 means
P2118 looks at how much current throttle motor A needs. A healthy throttle moves with modest current; a high or abnormal draw means the motor is fighting resistance. Ford lists P2118 with MIL and wrench lamp in its 2020-2023 summary (2024: P2100 byte 1D). The best-known trigger is a frozen throttle plate: Kia's 2022-2023 Carnival 3.5L bulletin describes limp-home mode after a cold soak and a revised ECM logic, Ram 1500 3.6L trucks get a de-icing kit (P2072, P2110, P2118), and Hyundai changed its hybrid ECM logic for what it calls ETC target position failure. Unlike P2101 (position error) or P2119 (spring return), this code points at the load on the motor. Bank B is P211C.
P2118 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible

Symptoms of P2118
- Limp-home mode after a cold start
- Engine warning lamp on
- No start or poor idle in frost
Common causes of P2118
- Most likelyIce on the throttle plate after a cold soak
- PossibleCarbon or sludge loading the motor
- PossibleWorn throttle motor or gear train
- Less likelyECM logic too sensitive (software 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 P2118 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. |
| 18 | The exact fault in that area. |
What to do next
- Note P2118 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 P2118
What does P2118 mean?
P2118 means "Throttle Actuator A Control Motor Current Range/Performance". P2118 looks at how much current throttle motor A needs. It is a generic code, so it means the same on every make.
Is it safe to drive with P2118?
Drive gently and only to a workshop. With P2118 the car can go into limp mode (reduced power) to protect itself.
Will P2118 fail an emissions test?
Yes, it can. P2118 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 P2118 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2118 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
