1992 toyota 4runner sr5 speedometer stopped working and check engine light illuminates

Hello Susan,

Your check engine light is located in your vehicles dash cluster and will only illuminate when a fault is detected..no detected faults..no light, although it should illuminate (to prove it is working) for a short period of time at each engine start up.

If your light does not confirm operation during the start cycle, explore for access to the lights wiring connector behind the instrument panel cluster to see if you can easily remove the lamp from the cluster...sometimes it it easier to remove the dash trim bezels and remove the cluster from the dash to change lamps.

Of course your Toyota's engine management systems are controlled by an computer generally referred to as a ECM (engine control unit (ECU), also commonly called an engine control module) so if your lamp fails to illuminate during the start cycle the problem may not be due to a simple lamp failure.

There could be several reasons why your engine will not start. When you first turn the key to the On position (without starting the engine), the lights on your dash should illuminate. The yellow Check Engine light should come on, at least for a few seconds. If not, then you are not getting power to your engine computer. Perhaps the fuse is loose. Locate the Engine fuse in the cabin fuse panel and wiggle it while watching the dash lights. When the Check Engine light illuminates, you should be able to start the engine. If not, then it is time to check for spark. You can remove a spark plug, install a jumper between the ground electrode and the engine block, insert the spark plug securely into the spark plug boot, and have an assistant crank the engine. If you see your spark plug firing, then you can assume you have a fuel delivery problem. Have the system pressure tested. You may have a weak fuel pump.

have the BCM checked for codes, this sounds like a communication problem between the BCM and other modules in the car.

check this fuse too..
The dash illumination lights run off of the TAIL fuse. Wierd I know!!
also a bad dimmer switch could very well be the culprit.

so why not scan it first and wonder 2nd.
that is what the light means, Im seeing errors ,please do scan me now
to see all errors
back in 1992 , DIY you have only blink codes.
my guess is the VSS CODE is set and the VSS is in fact dead.
google Toyota 1992 4runner DTC check codes.
i bet code 9 (use a paper clip at the CHECK term.)

or log in alldata.com and read. its all there ,all the time.

it and odometer?
only.
is the CEL lamp glowing running
did you scan the PCM for DTC errors. oops.?

I would wiggle the connector to the light switch it could just be a bad connection likely the master control for all the lighting

check the fuses in your manual it will tell you which fuses are for the dash and replace them it sounds to me like they are blown! good luck

Hi. You can reset the check engine light by removing the blue 15 amp EFI fuse (fuse box under the hood). If you do this, and the check engine light is illuminated again, you will need to address the cause for the light to be on; you have a 'hard fault'; and a part may need replaced.

look on the left of dash for the switch you turn your interior lights on turn it see if your dash light will brighten.turn up enough brighten dash lights. dont turn until it stop or your interior light will stay on.
