You'll need to check codes.

You can do it manually, but I recommend taking it to an autoparts store and seeing if they can do it for free.

To do it manually, you need to jump(bridge) 2 connectors on the diagnostic connector in your engine compartment. I can look up which ones, but try the auto parts store first.

Check the voltage of wires going to O2 sensor... if under 12 replace wires, had to do it on my car.

I did a similar thing to my Volvo v40 to the engine & airbag light. I took the dash off and removed the bulbs, and it ran without any problems for another two years. Even the MOT people didn´t notice it:)

I'm still laughing.

Your problem is a bum catalytic converter...probably...p0420 on obd2. But hey, if you don't want to bother checking the obd system feel free to keep throwing money at it.

That won't fly in the US because the tests are done from the obd diagnostic ports now (if it's obd compliant). Sniffer for older vehicles. You can't opt for sniffer tests (anymore) if you have obd as far as I know.

Is your gas cap on tight? Missing gas cap can trigger the check engine light on some cars

Challenge your programming.

It's not OBD2.

Toyota proprietary.

Call an auto parts store OP, and ask if they can scan it for free. If not, I'll tell you how to check it manually.

PM me if I don't notice your update.

RE: need help with a car
Just for S&G's, check your radiator overflow canister and radiator level. Make sure it is at level. This happened to me, canister was empty, drove me crazy for a week. How about the wiper washer tank?

Have you checked the manual or on line places to see if there is something that needs checking after so many miles? Not the usual sensors and such, but the catalytic converter, or something not normally considered? Gas cap, radiator cap in good shape? Thermostat working correctly? Gas mileage OK? Have you cleaned/replaced the EGR valve, PCV valve? Is the battery healthy?

Disconnect your battery for a few minutes, the lights should reset. If it comes back on, keep digging. The steady light itself indicates something needs to be looked at, if no performance loss, not a huge worry. If the CEL flashes, then that can be serious.

Don't find fault. Find a remedy. - Henry Ford

RE: need help with a car
Being a 1995 makes it a tad more difficult to diagnose... unless that y/m/m was one of the ones that went to the new engine management scheme a year early. You'd have to check and see.

1996 and newer cars and light trucks are what's known as OBD-II, whereas 1995 and earlier that have computerized engine management are OBD-I.

The OBD-I scheme is less unified, in other words different manufacturers can have different ways of coding these things, and they're more difficult to figure out just what the code(s) means once you have it.

OBD-I cars are less user friendly as well, many times even the specific code readers you can buy for them are really nothing more than a light that plugs into a pigtail under the hood and you still need to count how many times the light flashes to determine the error code, then dereference that number according to y/m/m to figure out what it means.

Whereas 1996 and later OBD-II has a neat interface and a much more one-unit-fits-all code reader that shows you the data and many even do some diagnostics and tell you what the code means without needing to go and Google it.

You don't have to spend anything to check codes. Sometimes the repair is a waste of time, but you want to be alerted if something important happens. So OP should spend some effort to shut the light off.

If you haven't done it yet, unplug the negative cable of the battery for a few minutes and reconnect it. (Car OFF, key OUT chuckle )That should clear the codes. If you already fixed the problem(through dumb luck) you're done.

If it comes back on, follow my earlier instructions.

Sometimes if you put gas in it causes a vapor pressure to build which will turn on tbat worry light. Go unscrew gas cap then put it back on.
