Hi this code is not on the chart you should erase the code and see if it comes back and if it does then check if it's P0446 and not 445

That is not a valid code for your vehicle or a dealer service code. Check this site for valid codes: www.obd-codes.com/trouble_codes/isuzu/

My 1999 Isuzu trooper blinked Check Engine


Hi Tony:
When the Check Engine Light is flashing ON it means that the computer has detected a misfire in the engine.It is not good to drive a vehicle that has a flashing check engine light; one or more sensor in your vehicle is advise about an code fault. I suggest scanning for know what code is in there and solve it.

In some vehicles, a red check-engine light means the car needs absolute immediate attention while a yellow check-engine light means you need to make an appointment soon. The light is used to indicate PCM (Powertrain Control Module) problems that are associated with your vehicle's emissions system.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Where is the diagnostic plug to get codes from check engine light


The 1990 Isuzu Trooper with a 2.8L GM engine, the diagnostic connector is located directly beneath the coin try in the front of your center console!!
Along with the typical OBD connector is two wires with a spade connector on each, one female and one male. Connect the two wires to display the diagnostic codes on your check engine lamp on the instrument cluster panel.
As for finding out your codes meanings, go to your nearest public library and locate a 1990 Trooper service manual.
