I can't read obd1 codes for **** evedentally. Can can you help me out and read them for me. Thanks in advance the video is a bit long 1:30 I think

 

Did you find where the codes are listed in "info threads", a sticky at the beginning of the forum? I didn't count your flashes and write them down, but if you do you should find codes listed that match your count. I did see a 5, a 9 ect. They are four digit codes with a space between them. Note that one pattern is "end of codes"

 

Looked like a 12, 75, 73, 35, 21, 21, 52, 55, to me.

 

Ya I know how to find the codes and technically how to count them.

A lot of those code numbers make sense. Thanks

 

ODB-I codes for us older jeeps..

11 No crank signal to computer. Fault in wiring between crankshaft position sensor (CPS) and ECM ( PCM or computer ) or faulty CPS.
12 Battery disconnected. Battery or power to the ECM disconnected in the last 50 key cycles.
13 MAP Sensor. No change in Manifold Absolute Pressure (MAP) between engine off and on. Check circuit and MAP sensor.
14 MAP Sensor. MAP sensor voltage too high or low. Check circuit and sensor.
15 Speed sensor or circuit. No signal detected from speed sensor. Check circuit and sensor.
17 Engine running too cold. Wrong or faulty thermostat. Check also sensor and circuit for fault.
21 Oxygen sensor or circuit. O2 sensor or wiring faulty.
22 Coolant sensor or circuit. Check temp sensor and wiring.
23 Intake air temp or circuit. Check air temp sensor and wiring.
24 Throttle Position Sensor (TPS) Check TPS sensor and wiring.
25 Idle Air Control circuit (IAC) Check IAC sensor and wiring.
26 Injector circuit resistance. Peak injector current has not been reached or injector circuits have resistance
27 Fuel injector control circuit. Will need specialist diagnostics.
31 Evaporative control circuit. Fault in fuel evaporative control circuit or hoses.
33 Air conditioning clutch relay. Wiring to A/C clutch fault.
34 Cruise control circuit. Fault in circuit.
35 Cooling fan relay. Check relay and circuit.
36 Air switch solenoid circuit. Air switch solenoid circuit (non-turbo) or the waste gate solenoid on turbocharged models
37 Torque converter clutch. Needs specialist or dealer diagnostics.
41 Alternator field switch. Switch not operating correctly and check charging system.
42 Automatic shutdown relay. Check relay and circuit. Needs specialist or dealer diagnostics.
43 Misfire. Misfire in one or more cylinders.
44 Battery temperature sensor. Needs specialist or dealer diagnostics.
46 Battery over voltage. Check charging system.
47 Battery under voltage. Check charging system.
51 O2 detects lean mixture. Check sensor and circuit and for vacuum leaks.
52 O2 detects rich mixture. Check fuel injection system and sensor.
53 Powertrain Control Module. PCM (ECM) fault. Needs specialist or dealer diagnostics.
54 Distributor sync pickup. Change sync sensor in distributor.
55 End of code. Trouble codes finished or none recorded.
61 BARO solenoid BARO solenoid failure
62 Emissions reminder. Emissions maintenance reminder. Needs specialist or dealer diagnostics.
63 Controller failure. EEPROM write denied. Needs specialist or dealer diagnostics.
64 Flexible fuel sensor. Flexible fuel (methanol) sensor indicates concentration sensor input more/less than acceptable voltage
65 Manifold tune value. Manifold tune valve solenoid circuit open or shorted
66 TCM to PCM failure. No message from the Transmission Control Module (TCM) to the Powertrain Control Module (PCM)
72 Catalytic converter circuit. Needs specialist or dealer diagnostics.
76 Fuel pump bypass relay circuit. Needs specialist or dealer diagnostics.
77 Cruise control system. Check power to cruise control solenoids.

 

Forward 02 sensor wires often get melted/ messed up on the hot exhaust manifold. There might be a start. If yer not in Ca or Hawiee a parts store might check or clear codes free.

 

the o2 wires got chopped by the axle hitting the oil pan actually. I call around here and no parts store can read obd1

 

I was told recently by our two local Advance Auto stores that they no longer will scan for codes. Orders from the top supposedly.

 

I had heard that can be an issue. A very rare DRB II, or a Snap-On 2500 with the correct cartridge might do it.

Btw, just disconnecting the battery over night should clear old codes. No harm in having something on there, dome light or headlights. One code you had I think was battery disconnected or some such. Not sure but that might go away after or before 40 starts.

Cool you found the 02 wire. An 02's five volt feed from the puter shorting can maybe freak some other stuff out. You might check fuses in your PDC, especially the mini ones here.
