To be sure, it's best to consult your owner's manual or a repair manual for your specific vehicle. It may also be helpful to visually inspect the engine bay for a black rectangular box with wiring harnesses connected to it.
Here's a general guide to help you locate it:
1. Open the hood.
2. Look on the driver's side of the engine compartment.
3. The ECM is often found near the firewall, which is the metal partition separating the engine compartment from the passenger cabin.
4. It may be attached to the firewall itself or mounted on a bracket.
5. Look for a black, rectangular box with wiring harnesses connected to it.
Remember, the exact location may vary slightly depending on the specific engine and trim level of your vehicle.
