Red lightning bolt light (electronic throttle)
The red lightning bolt on your dash — a bolt between two curved brackets — is the Electronic Throttle Control warning on Chrysler, Dodge, and Jeep vehicles. Typical causes are a failing throttle position sensor or a dirty or failed throttle body, and expect reduced power or limp mode while it is on. Show SightLine the dashboard and it walks you through the safe reset and when it is time for a shop.

Steps to fix red lightning bolt light (electronic throttle)
- Identify the symbol: a lightning bolt between two brackets is the Electronic Throttle Control warning on Chrysler, Dodge, and Jeep vehicles.
- Expect reduced power: the car often drops into limp mode with this light on, capping how hard it will accelerate in order to protect itself.
- Try the simple reset: pull over somewhere safe, shut the engine off, wait a moment, and restart — cycling the ignition can clear a one-time glitch.
- If the light stays on or keeps returning, the usual suspects are a failing throttle position sensor or a dirty or failed throttle body — some of these engines used throttle bodies with plastic gears that strip.
- This app cannot read your car's trouble codes — there is no scanner plugged in — so it will not guess which throttle part failed; a dealer or shop scan does that.
- When in doubt, do not drive — a throttle light that stays on, especially with hesitation or surging power, means get it to a shop soon, not live with it.
Safety first: DashRead has no OBD scanner, so it never reads or guesses a trouble code — it works from what it can see and what you tell it. A red oil-pressure, temperature, or brake light, or a flashing check-engine light, means stop now. When in doubt about whether it's safe to drive, don't drive — see a mechanic.
