Bunch of codes showing up. Help
I bought INNOVA reader and scanned the car (99 ML320). It gave read bunch of codes. Here are they:
P0100 - Mass or Volume airflow circuit
P0170 - Fuel Trim (Bank 1)
P0173 - Fuel Trim (Bank 2)
P0130 - O2 Circuit (Bank 1 Sensor 1)
10135 - O2 Heater Circuit (Bank 1 Sensor 1)
I just changes the plugs and fuel filter. Why would trim codes show up. Should I talk to dealer for this?
I want to know what can I fix myself. I am an engineer and have done some work on small motors.
If there are any procedures available please point me to them.
Thank you much.
