If you are running an engine check on your 1997 TJ, here is a list of codes that will help you determine what your current problem is.
How do I read my Jeep code?
Insert the key into the ignition.Switch to the “ON” position without starting the Jeep.Press the key and turn it three times to the “OFF” position, then to the “ON” position and pull it out to the “ON” position.
To run a test and easily determine which error codes it returns, run the followingshchie actions. Turn the big button OFF. -> ON OFF -> -> ON within 5 minutes. It takes a little time for checks and codes to show up right on the digital odometer display.
Does 1997 Jeep Wrangler have OBD port?
Exclusively up to 1997, they do not support OBD1 or OBD2. and you should have a 2 digit engine ECU code displayed on the dashboard if your correct engine has a DTC. Some codes turn on the engine light in a critical condition, some do not.
If you must have a 1998-2006 TJ, here is the code table.

Short or access condition detected in test cycle purge solenoid circuit.
An open, possibly short, has been detected in the speed control vacuum circuits or the purge solenoid circuits.
Switch input speed, note the minimum allowable voltage below. transfer
The relationship between website speed and vehicle speed clearly indicates that the torque converter clutch is engaged.
An open and short in torque has been detected in the torque converter partial throttle release solenoid valve circuit.
Invalid state of park/neutral switch input detected.
An open circuit or short circuit inside the generator can block the circuit.
An open or short circuit has been detected in the auto stop relay circuit.

Primary cutoff edge of the peak contour e is achieved at the maximum settling time. Found
Ignition rate in one or more tanks from 1 to 6. Temperature
Battery sensor when voltage is over or under range.
The battery voltage detection input is higher than the target value, emphasizing the voltage while driving.
Recommended battery voltage charges below target while driving. In addition, during active testing of the output oscillator circuit, no significant changes in battery voltage were detected.
The lean air-fuel mixture was determined by the effective correction factor for abnormally rich mixture.
A strong and abnormally rich correction factor indicates a productive air/fuel mixture.
An internal PCM error has been detected.
When starting the engineno camshaft signal detected.

The installer has detected a malfunction in the feedrate control of the servo solenoids.
How do I find the engine code on my Jeep TJ?
Within five seconds, turn on the main switch.Count the number of times the check engine light on the dashboard comes on and goes off quickly. The number associated with the blink is the error code. There is a short pause between the general flashes indicating the first and subsequent digits of the code.
If your 1997 TJ has a paycheck light on, here is a list of codes to help you find the problem.
To perform part of the test and find out which error codes were generated, do the following: turn the key -> OFF. -> ON -> OFF -> ON for a few seconds it will only take one bit for some current tests and additionally view all codes on dThe odometer display of your digital camera.
If you have a 1998-2006 TJ, you can find a table of these codes here.
