Check your fuel pressure, and or injectors. You may have too much fuel getting into the engine causing it to burn rich and overheat the converters.

Hi! You must be frustrated by now! your code is marking that the O2 sensor is bad in bank 1. Did you replace the O2 sensor that is located  before the catalytic converter?  The S10 has an O2 sensor specially made for that cat. its about 30$ That would explain for your blackened spark plugs; your pc on the car is asking for more fuel. GOOD LUCK!!

What does p0101 code mean


The mass air flow sensor is bad and needs replacing. It is located in the duct tube coming from the air filter to the throttle body. When this goes completely out then the car wont start. Until then it will have some power loss and fuel average will go down.

sir I am pretty sure it is the k and n filter...The oil inside the filter at times will **** through and dirty the maf sensor and throw this code...The metering cant hold a proper charge to measure air flow.I have seen this three times...I rcommend a denzo maf sensor and airaid cone air dryer or the mina gallery air dryer.These work flawless....and filter with a oil charge will cause this code.the other two codes are cyle and readiness codes that are performed by the cars ecu each time it is parked to check all modules for malfuction or codes...Remember codes are cycled between every two ignition or crank cycles unless you have complete failer of a module or drive train.

  • P0101 - Mass Air Flow (MAF) Sensor Performance
  • P0171 - Fuel Trim System Lean Bank 1
  • P0174 - Fuel Trim System Lean Bank 2
  • Would start with the mass air flow sensor the other two codes may have been triggered by the performance of the MAF sensor. Is the vehicle running poorly or have high or low idle?

    Those are lean codes and a MAF (P0101) code. Make sure the MAF sensor is plugged in, and there are no leaks/ loose hoses between the air filter and the engine. You may have a vac leak at the intake also, but check these first, If all appears OK a repair shop will need to check it out for you.
