Question about 1992 Toyota Corolla

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??

Thanks Heaps

2001 Montero Sport up stream oxygen sensor has failed. My check engine light came on and tried to drive vehicle at night and my lights went dim and the truck quit.


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 )

Tail lights dont go on


Most likely a fuse or circuit breaker. Check your fuse box for a blown fuse. I assume your brake lights still work. Yeah, that's scary alright. You were lucky not to get a ticket.

I would greatly appreciate a list of check engine light codes for a 91 dodge spirit. I believe the code it put out was either: 1,2,4,7,5,5 3,4,7,5,5 This is for my girlfriends daughter, she was away at...


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.

Check engine light and strong fuel smell when stopped with heat on.


Hi Shawn,

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.

I hope that helps.
