Question about 2004 BMW 3 Series

1 Answer

My 04 325i SES light came on after I hit some debris. The mechanic (BMW w 25 yrs experience) said the code was for the ambient temp sensor. Sensor and wiring harness replaced and the light stayed on. Then he said it must be one of the horns - fixed. Light still on. Now I'm being told it's a phantom code! I don't want to miss something. Any suggestions?

Horns? Phantom Code? BS. You may need to have another shop that specializes in BMW to check it out.

I have mits triton nov 2009 4x4 the ambient p0072 makes the eng light come on but it does not have that sensor so I need to know if any knows the colour so I can check wiring thanks


code p 0072 refers to outside air temp sensor ( ambient temp sensor--low input===causes ---wiring short to ground, outside air temp sensor ---ECM
thee has to be an ambient temp sensor as that reports the temp to the ECM to adjust the air/fuel settings for cold starts
it could be in the MAF/VAF sensor area

Codes po171 174


Here we go.... just pulled out our service ticket:

Soooo interesting, I had never looked at these before:

So on 1/10/2005 we took the Vue in, and they did the following:
date: 1/10/2005
"CUSTOMER STATES THE SES LIGHT IS ON"
CAUSE: UNKNOWN
TECH COMM: SES LIGHT IS ON. FOUND FUEL TRIM LEAN CODE P0171 & P0174. RETORQUE INTAKE VACUUM CHAMBER BOLTS AND INSTALL VACUUM CHAMBER SPRINGS PER BULLETIN02/06/01/016A

REPAIR 1: INLET AIR CONTROL VACUUM RESERVOIR - REPLACE


Then, evidently it came back on a week later:

date 1/17/2005:

LINE1: "CUSTOMER STATES THE SES LIGHT IS ON"
CAUSE: OPEN
TECH COMM: SES LIGHT IS ON.
FOUND CODE P0171 FUEL TRIM LEAN B1 CODE P0174
FOUDN MASS AIR FLOW SENSOR FAILED REPLACED MAF SENSOR


...

The problem NEVER came back..

There's my experience. Good luck!

I replaced my temp sensoe and it reads ccd


Hi Glenn, I'm glad to help! Here's how you check the Ambient Temp Sensor circuit itself to see if its working properly. Disconnect the Ambient Temp Sensor Connector. If the temp reading go to the default mode it will show 40 degrees. If it doesn't go to 40 Degrees then thyere something wrong with the system. Could be wiring or display itself. If it does go to 40 degrees then I'd try another sensor and see what happens. Hope this helps and have an awesome day Glenn.

2002 bmw has no heat def,or heater .start up error -40deg dash


The ambient temp sensor is out of range maybe came unplugged or is faulty or the computer that reads the sensor is faulty or has a bad connection most ambient sensors are located behind the front grill and are pretty easy to get to enclosed is a typical bmw ambient sensor you didnt say your model so this is just a general idea 1_4_2013_5_06_15_am.jpg

Ambient sensor gauge stopped working correctly at the same time the AC quit


The ambient temp sensor is related to the AC function, if the HVAC system thinks the outside temp is too low, the AC will not be turned on. You probably have a defective temp. sensor. It is easy to change and relatively inexpensive. It is located on the underside of the top radiator support almost in the center (just to the drivers side of center).
The car dying at a stop light can probably be solved by cleaning the throttle body. Make sure that both the front and rear sides of the throttle body are cleaned. And also disconnect the battery during the cleaning process, this will reset the computer and allow it to relearn to the cleaned throttle body.
The compass issue is another separate issue and may just require a recalibration. I don't know what the procedure is but try Googling the subject.

Air conditioner will not come on. The tempeture gage is reading -40. The sensor is not reading properly.


Hi ruswashingto,

The air conditioner may not work properly if your ambient temp is reading -40. The a/c control unit monitors ambient temp so that it does not operate at too low outside temps. I would recommend fixing the ambient temp sensor and rechecking your a/c operation.

Code: Insufficient Catalytic Converter 1? I replaced the catalytic converters on my car at a local muffler shop and afterwards the SES light came back on. The code says insufficient catalytic converter 1....


You should have changed the front o/2 sensors if any. The rears just read what the cats are doing and the fronts control the fuel feeds to the engine. Using Aftermarket cats is usually a hit or miss prop on the p0420. U need to find a shop that can really diag this for you because it sounds like only one bank is coding for you therefore bank 2 is ok. Go to IATN.com and find a good mechanic.
