P0173 Fuel Trim Malfunction (Bank 2) - OBD Codes

Detailed information on troubleshooting and repairing a P0173 DTC code which refers to a fuel trim malfunction on Bank 2. Also includes links to relevant forum ...

I would recommend checking for an intake air leak. Under the intake is a crankcase vent valve that can rupture as well as lines connecting to it. I would also check the rubber bellows from the air mass meter to the intake and make sure they are not split or torn which is also common.

p1188 is fuel pump and p0170 is same problem but with air flow sounds like drawing in too much air and not much fuel. pump might be shot.

hope this helps

P0304 = #4 cylinder misfires
P0170 = Fuel Trim, Bank-1
P0173 = Fuel Trim, Bank-2
P1250 = this is invalid code for BMW
P1188 = Fuel control, bank-1, sensor-1 (pre-cat sensor)
P1189 = Fuel control, bank-2, sensor-1 (pre-cat sensor)
Vacuum leaks and/or sensor defective for the issues of the codes.
This error codes really need parts to replace. But you have to replace the thermostat first. Then clear the codes and see if any reappears,then replace defective part/s

James,

Based on the numerous codes and others who have experienced many of these problems, I would say you have a vacuum leak near the intake. I would also clean my DISA and ICV as well.

Please buy a Peake code reader (No..I don't sell them but I can vouch that they save time and money in the long run. A generic code reader will have you throwing thousands of dollars into repairing your car that aren't needed.). The Peake code reader is BMW specific and gives a more detailed result because the reader scans BMW specific codes that a generic OBD 2 reader can't.

This guy has an excellent video on how to clean your ICV and I think he has one on the DISA (which is next to the ICV):

Hope this helps!

los tres codigos hacen referencia a malfuncion en control de combustible , pero si aparecen los tres a la vez es muy probable debido a filtro de gasolina sucio

These codes will have to be cleared and the car driven through a drive cycle, maybe a couple of times, is the check engine light off? Also you should check your MAF sensor it may need to be cleaned or replaced and makes sure there are no holes in your intake tubing. Hope this helps, let me know.

all the codes you have are all related to the fuel trim, this problem needs to be looked at with a european capable scanner for futher tests sorry.

SAE Code P1188 DTC Code 17596 Description Linear 02 Sensor / Compensator Resistor Short to ground SAE Code P1189 DTC Code 17597 Description Linear 02 Sensor / Compensator Resistor Short to B+ SAE Code P0170 DTC Code 16554 Description Fuel Trim, Bank1 Malfunction

Basically you need a new oxygen sensor, The fuel trim code is from the computer trying to adjust the fuel/Air mixture to compensate for the bad signal from the sensor. Just change the one closer to the engine, the one behind the Catalytic converter will thow a different code when it fails.
