Intermittent electrical problem 1992 toyota trueno/levin AE101
Last night as I was driving my car home, I noticed the overheating/O2 sensor light came on, then I noticed that the check_tail_light and battery lights had also come on and started the swear to myself, As I pulled over to check they all went out... confused I took off again and hey presto they came back on again... I did this several time until i isolated that they were comeing on at about 1550 rpm in first and would go out at the same revs. I then thought screw can't be bothered with this then ignored them and carried on driving home - but after about 10k's the battery voltage indicator started to creep up and I had to turn on all my peripheral electronics to try and keep it under 18V...
This is my first car and having owned and worked on motorbike most of my life I am assuming that they are similar, I going to get it load tested this afternoon but and other advice would be hugely appreciated
also - where would I find the regulator/rectifier on a car and do they even have one??

speed sensor or wheel bearing as well brake problem or burnt fuse a few things to check if worst comes to worast unplug battery and replug battery wait 15mins before plugging battery back then go for a ride if it lights up as soon as you start there is a power problem or sensor problem if you drive it and comes on latter then you have a sensor problem or brake problem
This has nothing to do with you O2 sensor. You have more than one problem. An O2 sensor will not cause what you just described. It will cause a check engine light but not the dimming of lights and a stalling issue. Check your charging sytem ( battery and alternator )
Not absolutely sure on the codes given. You can buy a Haynes or Chilton Manual at most auto parts stores for the vehilce. $20-$30. For a 1984-1995 Caravan the following codes are:
Code 12 = Number of key-ons since last fault or since fault(s) were erased. Battery to controller disconnected within last 50 to 100 ign key on's.
Code 24 = Throttle Position Sensor low voltage.
Code 34 = Speed control solenoid circuit. An open or shorted condition in the speed control vent or vacuum solenoid circuits,
Code 47 = Charging System too low. Battery voltage inut below target charging during engine operations. And no significant change in voltage during active test of altenator output.
Code 53 = Internal controller failure. Internal engine controller fault condition detected.
Code 55 = Completion of Codes.
Code 51 & Code 52 = O2 Sensor problems.
Buy the book to verify and compare.
It sounds like it might be the oxygen sensor failing on your car. If it *is* the O2 sensor, it's not that expensive, from $50 to $200 and may be something you can replace yourself. But it's very unusual to have an O2 sensor fail so early. They typically last 60,000 miles or more.
At any rate, you really should get it checked soon. Running with a very rich fuel mixture will cause the catalytic converter of your exhaust system to overheat and cost many hundreds of dollars in additional repairs. It can also cause a grass fire if you park over dry grass with your overheated catalytic converter.
The first thing a mechanic will do is hook up a code scan tool to a connector in the car. This tool will show the error code that your engine's computer is complaining about. That code will probably point to the O2 sensor or something like that.
