Bmw 335xi P0139 Engine Error Code

When you check Bmw 335xi car engine light came on code P0139 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However Bmw manufacturer may have a different definition for the P0139 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.

P0139 Bmw 335xi engine problem can be occur defective fan clutches are a common and often overlooked cause of engine overheating. The shear characteristics of the clutch fluid gradually deteriorates over time, with an average loss in drive efficiency of about 200 rpm per year. Eventually slippage reaches the point where effective cooling is no longer possible and overheating results. (On average, the life of a fan clutch is about the same as a water pump. If one needs to be replaced, the other usually does too.)

Bmw 335xi P0139 OBD-II Diagnostic Powertrain (P) Trouble Code Description Bmw 335xi car P0139 OBD-II Trouble Code The Heated Oxygen Sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. For optimum catalyst operation, the air fuel mixture (air-fuel ratio) Reason For Bmw 335xi P0139 Code The reason of Bmw 335xi P0139 OBD-II Engine Error Code is P0139 O2 Sensor Circuit Slow Response Bank 1 Sensor 2.

OBD P0139 Bmw 335xi code and tailpipe testing are two different approaches to identify vehicles in need of repair. The OBD system looks for broken or malfunctioning emissions control components and , while tailpipe tests sample a vehicle's exhaust to see if it is above or below certain prescribed limits. Given the robust nature of today's emissions control components, it is entirely possible for an individual component to P0139 Bmw 335xi malfunction without leading to an immediate increase in emissions at the tailpipe. In such cases, other components (like the catalyst) can temporarily compensate for the part that is broken however, these other components can only do double duty for so long before they, too, begin to malfunction. In addition, OBD also monitors for P0139 Bmw 335xi and other malfunctions in the fuel system problems that traditional tailpipe tests were not designed to identify. Most state and local areas also include a gas cap pressure test as part of an emission inspection.
