This refers to your catalytic converter located on the exhaust system. This can possibly be a problem with one of the oxygen sensors used to evaluate catalytic converter performance.

1999 chevy blazer 4wd 6 cyc 4dr code P0420 Catalyst System effecency below threshold Bank 1 confirmed


There is a chance that your temp sensor is the culprit on both codes. The temperature sensor is what tells the ECU how hot or cool the engine is and weather or not to keep the engine in phase lock loop, or choke, mode. If the engine stays in phase lock it will run too rich and the O2 sensor will not be able to compensate.

You'll have to contact the dealer to find out the security code or have them tell you how to disable your cars security system. The only other way to do it would be to disconnect the battery but if you've already tried that then nothing else will work other than have the code.

REplace the temp sensor then top off the coolant to avoid overheating. Fan will not work cuz sensor doesn't send signal that the coolant is hot enough to warrant a cooling from fan.
