Question

2004 acura tl 3.2 automatic zip code 92603

Answer 1

P2237 Rear A/F sensor  (Bank 1 Sensor 1) IP line voltage high

P0174 Front Bank (Bank 2) Fuel system too lean

P0154 Front A/F Bank 2 Sensor heater system malfunction

P0134 Rear A/F sensor (Bank 1 Sensor 1) heater system malfunction

P2254 Front A/F Sensor (Bank 2 Sensor 1) VS line high voltage

The code you need to take care of fist is P2254, P2237, These code will set a P0174 , P0154, P0134. Circuit high voltage occurs when the ECM does not see a connection of the A/F sensor. this can be from a poor connection to a open connection.or a failed A/F sensor
