How many computers does my truck have?
Hi, thanks for writing in. An Isuzu NPR should have one ECM (engine control module), which is the computer. This is the brain of your vehicle. It is what regulates your fuel to air ratio as well as all electrical. If you would like help with an electrical part of your car, consider having an expert automotive technician from YourMechanic come to your home or office to inspect your vehicle for you, and make or suggest any repairs as needed.
