Did a diagnostic scan on my Lexus Rx 300 2001 model and got these error p0174 and p0420. Please can someone in the house enlighten me more on what they mean? And possible solutions. Thanks

P0420: catalyst efficiency code. The most common thing is the catalytic converter itself going bad. The other likely thing is the rear O2 (oxygen) sensor going bad. Other things could include exhaust leaks, damaged exhaust pipes, damaged O2 sensor wiring/connectors, plugged catalytic converter, etc.

P0174: means the MAF (Mass Air Flow) Sensor is dirty or faulty. this can happen when your air filter has become very oily. Remove the MAF sensor and have it cleaned. if this doesn't solve the problem, have the MAF sensor replaced. Please don't rule out the possibility of faulty wiring harness to the MAF.

Thanks very much decotech
