For example, code 16 = 1 flash * Pause * 6 flashes. There will be a longer pause between the codes if you have several trouble codes and a shorter pause between the trouble codes’ digits.
Low voltage can cause a lot of trouble with the troubleshooting and many error codes that we do not want. Always connect a car battery charger to your car when doing any electrical work that requires the ignition to be on.The car will then enter the diagnostic mode and flash the “ check engine Light” several times, and we should count the flashes to figure out the diagnostic codes. Our reading method without a diagnostic tool is to make short the circuit of pin A and pin B. Power management – Error / faulty circuit Ignition control (IC) 3X – Signal error/faulty circuitĪnalog/digital – Pcm error /faulty circuit Vehicle speed sensor (VSS) – Circuit signal low resistance Vehicle speed sensor (SS) – Circuit signal high resistance Gear selector switch – Circuit error/faultĪ/C (Air conditioning) Evaporator temperature – Circuit high Oxygen O2 sensor right side – Rich mixture indicatedĪ/C (Air conditioning ) pressure sensor – Circuit low pressureĪ/C (Air conditioning ) pressure sensor – Circuit or a/c clutch – circuit failure (depending on the car model)Ī/C (Air conditioning ) compressor relay – Circuit failure errorĪ/C (Air conditioning ) clutch – Circuit/pressure highĪ/C (Air conditioning ) refrigerant pressure – Circuit highĪ/C (Air conditioning ) evaporator temperature sensor – circuit low Oxygen O2 sensor right side – Lean mixture indicated

Check your repair manual for the trouble codes of your car model. We do not take responsibility for any faults in this code list. The OBD1 codes’ meanings can differ a bit depending on what car model you have, but most of them are the same among all car manufacturers. Here is a complete OBD1 trouble code list.
