Diagnostic code for '95 Saturn SL

My son is getting 2 codes (22 & 83) on his diagnostic meter. Acccording to his manual there are no 22 or 83 codes. Can anyone give us the proper code(s)? The car is a dual overhead. I really appreciate any help for him. Thank you very much.

My manual shows----- code 22 is throttle position sensor, and code 83 is low engine coolant.

I have a 95 buick le saber 3.8 ltr. It back fires when running. But when check engine light is on it wont back fire. It does sound louder with check engine light on. Changed coils. I need help trying to...


You need to scan the computer for trouble codes. If the light was on, there must be codes set. On a '95 Buick, it would be OBD-1, On Board Diagnostics-first generation ('96 and later is all OBD-2).
The diagnostic connectors are different for OBD1 and OBD2, but in '94 and '95, GM was on some models using a "hybrid" diagnostic link connector. You will just have to find the right diagnostic connector to get your codes. The guys at autozone or a national parts store who do engine scans for free may help you figure it out. If it is a straight forward OBD 1 connector, a cheap code reader could scan for trouble codes. For the OBD1, you can also use a jumper wire between terminals
A & B of the diagnostic link connector. Turn key to on, and two digit codes will begin to flash on the check engine light. Code 12, for instance, would be a flash, pause, two short flashes, and longer pause before the next code appears. Code 12 by the way, just means that the computer is in diagnostic mode-after that any set codes will appear or be flashed. Code 55 may also be flashed-this code means the end of codes that are set.

Tip

93 Saturn SL2 Does Not Start, MIL Light On


Hi, here are procedures from autozone.com for extracting trouble codes from your Saturn:

See Figure 1
To enter the self-diagnostic mode, either connect a scan tool to the ALDL or DLC. On 1991-95 models, use a jumper wire to connect terminals A and B of the ALDL. Turn the ignition switch ON , then the PCM will enter the diagnostic program and report trouble codes on the scan tool or by flashing the SERVICE ENGINE SOON light.
All codes are 2 digits between 11 and 99. Codes are displayed on the SERVICE ENGINE SOON light by flashing the light with short and long pauses to distinguish digits of one code from digits of another. The short pause is used between digits of the same code, long pauses are between different codes. For example, the Code 12 sequence will be: flash, pause, flash-flash, long pause.
  1. When the diagnostic mode is entered, Code 12 is displayed 3 times. This indicates that the internal diagnostic system is operating. If Code 12 is not displayed, the self-diagnostic program is not functioning properly. If only Code 12 is displayed, no system malfunctions have been stored.
  2. Any existing system fault codes are displayed in order from low to high, except for Code 11. Each code is displayed 3 times, followed by the next code, if any.
  3. On vehicles with an automatic transaxle and on which exist stored transaxle codes, Code 11 will be displayed last, then the SHIFT TO D2 (1991-1992 models) or HOT (1993-98 models) light will begin flashing transaxle codes or flags.
  4. When all engine and transaxle codes have been displayed, Code 12 will flash again. At this point, all output devices are driven, except the fuel pump, so these circuits can be checked.
  5. This procedure can be repeated as required by cycling the ignition switch OFF , then ON again with the ALDL terminals jumpered together. The code display will begin again as in Step 1.

Here are some tests for the MAP sensor:
See Figures 1, 2 and 3
  1. Unplug the MAP sensor connector and turn the ignition switch ON . Check for about 4.5-5 volts between connector terminal C (gray wire) and ground.
  2. Check for the same voltage between terminals C and A (black wire). This is a ground through the PCM.
  3. Reconnect the wiring, then install a Saturn diagnostic probe, or equivalent, on the green wire and connect either a voltmeter probe or a scan tool to the ALDL. Connect a vacuum gauge to the intake manifold.
  4. With the ignition switch ON and the engine not running, the return signal voltage should be close to the supply voltage in Step 1, if below a 1000 ft. (305 meters) altitude. If above this altitude, see the chart for the correct voltage.
  5. With the engine at idle, there should be at least 16 in. Hg (54 kPa) of manifold vacuum and 1-1.5 volts on the signal return wire. When the throttle is opened suddenly, the signal voltage should increase. It may only change momentarily.
  6. If the voltage at idle is the same as in Step 1, or if the voltage does not change when the throttle is moved suddenly, the sensor is faulty and must be replaced.

How do I reset obd codes 1996 Saturn SL2?


Soft reset is disconnecting the negative cable battery few minutes; if your codes come on again, need some scanner reader codes tool to know what code is stored and diagnostic to solve it.

Feel free to contact us in this code link, if you need additional details.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Where is the diagnostic port on 1995 saturn sl1


DIAGNOSTIC OR ASSEMBLY LIND DATA LINK LOCATED UNDER THE DRIVER SIDE DASHBOARD NEAR THE KICK PANEL TO RETRIEVE TROUBLE CODES USE A JUMPER WIRE TO B AND A TERMINAL TWO TOP FAR TO RIGHT TERMINALS SIDE BY SIDE B AND A . CHECK ENGINE LIGHT WILL GIVE YOU MORSE CODE.LIKE TWO FLASHES PAUSE FEW SECONDS THEN FLASH THREE MORE TIMES THAT IS CODE 23 BUT A CODE SCANNER QUICKER BUT JUMPER WIRE CODE TRICK WORK AS GOOD IF YOU DONT HAVE CODE SCANNER. BUT YOU NEED CODE BOOK TO SEE WHAT CODES YOU ARE RECEIVING FROM PCM.

I have diagnostic codes of 22, 23, 24 for my 1995 Saturn Sl 1


well according to your codes that i looked up for you i think its safe to assume that your timing is off. i will paste the codes so you can see for your self. i hope this is what the codes actually look like.
P0022 "A" Camshaft Position - Timing Over-Retarded (Bank 2)

P0023 "B" Camshaft Position - Actuator Circuit (Bank 2) - See Trouble Code P0020

P0024 "B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2) - See Trouble Code P0021

P0025 "B" Camshaft Position - Timing Over-Retarded (Bank 2) - See Trouble Code P0022
