The Loyale is a bit tricky to diagnose since it is Pre-OBD2, harder to access the codes to determine why the Check Engine light is coming on, which is the first step in diagnosing this.

First, is the car still operating normally, no driveability problems since the CEL came on?

Now, the easiest way to find out what code is displayed we need to drive the car, when the CEL in the dash comes on, you will need to safely pull over, and while the light is on, read the flashing light on the Computer control unit that is under the drivers side dash, mounted directly under the steering column, you may want to remove that cover under the dash ahead of time, so you can have an easier time reading the code . There will be a little hole in the computer, on the side of the computer facing the drivers seat, in this hole is a red light that will blink, when there is a problem, the light blinks a code automatically. You have to read the "blinks" say you see the light flash slow 2 times and then fast 3 times..that would be a code 23, so you get the idea, watch the blinking a few times to verify what code or codes you get, this way you can let me know the code/codes and then we can further diagnose this problem. Good luck.

Let me know, Kevin C.

yo Kevin, sorry to take so long to get back to ya...my message was lost and was just able to get back in yesterday -

drivability is not apparently affected - but will be checking mpg

I did as you suggested and found the cpu under a maze of wires - yep there was a hole in the case and it was blinking a slow 3 and a fast 4 = 34

I'll be checking it again as it constantly is on yet off occasionaly - on my 25 mile commute home last night it was off until I was caught up in traffic - sure enough as I shifted from 2 -3 it came on - weird that it does that - your assistence is appreciated

Expert:  Kevin C. replied 3 years ago.
Code 34 is a common code for the Loyale, it's an EGR Solenoid failure. It's located under the hood mounted near the throttle body. You may be able to get one aftermarket, it will not cause the car to stop running but it may be a good idea to replace it when you can..You may notice a little "gas ping" if you don't.
Customer: replied 3 years ago.
at first I was unable to locate an EGR solenoid valve - parts houses did not find any for me - until yesterday. I'm awaiting for the part to show up and then see if it silences the ECL. in the meantime the brake light just came on, I checked and the fluid resorvior was low, so I added some fluid but am wondering where that fluid has gone - I looked for leaks at the res, and checked wheels - but have not pulled the wheels off the car, brakes seem to be working so?
Expert:  Kevin C. replied 3 years ago.

I would check the brakes for worn pads, that can reduce the level of fluid in the reservoir.

part came in yesterday and installed it minus some skin off the old knuckle, and a new EGR valve, as of yet no CEL - thanks! I replaced brake pads a year or so ago but I'll pull a wheel and check them out
Expert:  Kevin C. replied 3 years ago.
Also may want to pull the rear drums and check for a leak at the wheel cylinders.

So, How's your Check Engine Light? Fixed?
