pull the ECU /PCM memory fuse'
or pull battery neg lug for 5min, or more.

the fuse on a wrangler 92 is. fuse #5 (wt/yl wire color) 10 amp

try turning the headlight knob left to right several times, and jiggle the switch at night. Also check your fuse panel should be a 10 amp or less fuse that says "Insr" or something like it.

Code 12; Means the battery was disconnected within the last 50 key-on cycles. Ignore this code.

Code 24; Throttle position sensor input voltage is above the maximum acceptable voltage.

Code 17; Engine is cold too long. engine coolant temp remains below normal during vehicle travel. (thermostat)

Code 55; Means end of message/codes.

Your problem is most likely due to a defect thermostat that is stuck open. Replace the thermostat.

wall5552: there were two engines used in 1992 Jeep Wranglers.
A 2.5 liter and a 4.0 liter. HOWEVER>>>> The location for the crank angle sensor is the same for both.
It is located on the bell housing up near the front at about the 10:00 PM position.
The Cam position sensor is located in the Distributor on both engines as well.

Open the hatch, there are some 10 millimeter screws on the inside. Take those out, gently pull on the whole taillight assembly. the whole assembly should come off. Then turn the light plugs counterclockwise, change the bulbs. Be very careful - these bulbs can break when you squeeze them to pull them out.
