CE Light On - Code 50

[RageRover]

It was again a matter of time before the Check Engine light came on. It did so today, on the freeway. No effects to the engine, or anything. Drives normally.

So what does code 50 mean? This is the number I saw on the display under the passenger front seat.

This sounds like it might be a maintenence code that was thrown, but I have no idea.

Here you go.

To clear it disconnect the battery neg for 15 secs or so to clear it out. If it comes back then I would persue it.

Code 40 - Misfire bank A - left bank
Code 50 - Misfire bank B - right bank

If both codes are displayed, check the following components common to both banks:
Distributor cap
Rotor arm
Coil
Electrical connections
Pick-up (air gap)
Amplifier
Injectors (if code 34 or 36 is displayed)
If either fault code 40 or 50 is displayed check components applicable to the particular bank that the misfire has occurred on.
Spark plugs
HT leads
Distributor cap
Injectors - if code 34 bank A or 36 bank B displayed

Ok, thanks Franky. I will try that here in a minute, as I am bored as brick right now. If it don't work, I will test the ignition system, starting with the basics. I just hope it don't lead to injectors.

Any idea what it means by Amplifier? Have something to do with the ignition? Kinda doubt that is, what ever it is, is the problem.

But we'll see once I disconnect the neg. batt. lead.
