Po42 and po43 on my gmc 1991 1500


That means both bank one and bank two oxygen sensors are reporting the same signal IN FRONT OF and BEHIND the catalytic converter. This could be from the catalytic converter failing or it could be from a manifold leak, wiring problem etc.

I have a 1999 dodge ceruis. I quit running going down the highway at 70 mph. It was very low of oil. Do the have a ciser shut down system


You are fortunate that the engine still cranks. If it overheated when it shut down it is possible that some of the electrical components may have been burned out.

And if you did permanent damage it is possible that now the engine is not cranking fast enough to start.

Good luck.

There is no problem only the service engine soon light is on and the car failed the emission test. The diagnostic trouble codes is po43


A code P0430 may mean that one or more of the following has happened:
  • The catalytic converter is no longer functioning properly
  • An oxygen sensor is not reading (functioning) properly
  • There is an exhaust leak
If the Ox sensor has never been replaced I would do that.. Its a lot cheaper than the CAT. The one that needs to be replaced is AFTER the Catalytic Converter.

A good shop should be able to tell if this is your issue or not though.
