Warning light

[JSRInc]

Have a '92 Suzuki carry that a customer has had trouble with carb flooding. I noticed Saturday it also has a warning light in the upper right hand side of instrument panel (between speedometer and fuel gauge). It has two parallel lines running horizontal, one parallel line on each end, and about four wavy lines running vertical. What is the warning and could it be contributing to the flooding?

I have a subaru that had the same light. It ended up being a wire broke off of a sensor found on the exhaust. I would think its either the wire or the sensor on yours. I dont think it has anything to do with the flooding. I'm not a mechanic, it just my opinion from my experiences. Hope it helps.

I'm going to ask my mechanic about this, and we'll look at the Japanese owner's manual. Hang tight for a day.

According to our mechanic:

What you're seeing is the engine overheat light
He said that either the sensor is bad... or there is water getting into the engine and that you could check the oil. If the oil is a creamish colour, then water got into the engine and you'll have to change the gaskets.

I hope this helps. Please remember, without seeing the truck we can't give a proper diagnosis, but that may take you in the right direction.

By the way, this is the light you were talking about, right?

That's the light. The temperature gauge is showing normal.

That light looks like it's indicating a plugged cat or hot exhaust.

That light has to do with the exhaust system.....There are several threads on this forum about this light and the associated fixes.

So your sensor must be bad if your temp is ok. I've seen this before. I'll ask about that the fix (if its a quick fix) can be.

I guess I spoke too soon. But, I'll still see what a fix could be.

Yes.. the light is wired into an exhaust temperature sensor, usually near or in the catalytic converter. It can be activated by:

Having a bad or broken connector (most common)
A bad sensor
Improperly timed ignition (which can heat up exhaust)
A clogged converter
Faulty carb resulting in lean condition (apparently not happening)

Possibly too much raw fuel in the exhaust has messed the sensor up?
