O2 Sensor Circ.,Bank2-Sensor1 Voltage too Low/Air Leak
Exhaust Gas Recirc.Flow Insufficient Detected

Fuel Trim,Bank1 Malfunction

Fuel Trim,Bank2 Malfunction

Fuel Trim,Bank2 System too Lean

Hi...these are the trouble code definitions for your make, model and year.

They point to an egr, o2 sensor and fuel injection system problem.

Print this page, take it to a service facility that is familiar with Audi vehicles( preferably an local Audi dealer with a service facility).

Show them this print out and ask for a estimate on repair.

Being that you already have the codes, you should be a step ahead being that they don't need to hook it up..but..they may do it anyway to see if there are more than have cropped up or perhaps gone away since you obtained these.

At any rate, my feeling is should save yourself alot of money by being able to point them in the right direction right off the hop.

Should you need help finding a dealer /service directory, go to and follow the link at the bottom of the page.

Hope this is of assistance to you.

Happy Motoring.

What is the code p0174 and p0173 in my 1998 accura rl

That's what happens when you change parts based
on a code & never test anything

Both codes are for bank #2 on the engine

One is Fuel Trim Malfunction & the other
is Too Lean (all the same issue)

Need a repair shop to properly diagnose

No need to tell me that it was at a shop already

THEY FAILED TO FIX IT--stupid,sloppy workmanship

NO TESTING --to find route cause of codes

Are you sure it is a trans code. Everything that I have found states that P0170 is a fuel trim problem?P0170 Fuel Trim Malfunction (Bank 1)

The code P0170 means that the air-fuel mixture coming in to the engine is too lean, or too rich. Usually it's the lean condition that causes this code. The code P0173 means the same, only for the Bank 2. Some car manufacturers list the description for the code P0170 as self adaptation out of limits.
The code P0170 could be caused by a number of reasons, such as vacuum leaks, bad PCV valve, or other parts of crankcase ventilation system, low fuel pressure, bad oxygen sensor, bad MAF sensor or even a bad EGR vlave.

Have codes p0170, p0174 and p1518. Car is a 2001 Firebird 3.8 w/ T5.

P0170 and P0173 means that the system tried to go outside of the fuel trim limits.
Now this can be usually caused by a bad mass airflow sensor, but there's number of other reasons why the engine cant stay with predefined fuel trim limits. There might be an unmetered air in the system, an injector could be faulty, lambda probes might have shifted charactereistics...indeed, in most cases it's the MAF itself, but careful - i've got some returning customers after "quick and dirty" diagnosis of faulty airflow senso

Troble code P0170

Trouble Code: P0170 (3.4L V6 VIN V Auto)
Fuel System Too Rich or Too Lean (Bank 1) Print this code dataprint_icon_codes.gif Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
DTC P0100, P0101, P0110, P0115, P0120, P0121, P0130, P0133, P0136, P0135, P0136, P0141, P0153, P0155, P0201-206, P0300, P0301-P0306, P0401, P0402 and P0441 not set, engine running in closed loop at a stable engine speed, and the PCM detected the lean or rich fuel trim correction value was more than or less than a calibrated limit in memory.

Possible Causes:
  • Air leaks present in the exhaust manifold or exhaust pipes
  • Air being drawn in from leaks in engine gaskets or other seals
  • Base engine "mechanical" fault affecting one or more cylinders
  • Fuel control sensor is out of calibration (i.e., ECT, IAT or MAF)
  • Fuel delivery system supplying too much or too little fuel at idle or cruise (e.g., faulty fuel pump or dirty, restricted fuel filter)
  • One or more fuel injectors is dirty, leaking or stuck open/closed
  • HO2S element is contaminated, damaged or it has failed

The codes are for the Mass Air Flow Sensor. It is located between the throttle body and the air filter case. You will see it has a plug in the side. Unplug and remove it by taking the hose clamps off each end. Once you have it out, clean it out with a good throttle body/intake cleaner. Allow it to dry and reinstall. If the light continues to come on, you will need to replace it. Cleaning has worked for some.
