2005 Bmw 428i Xdrive P2146 Fault Code Check

When you check 2005 Bmw 428i Xdrive car engine light came on code P2146 the reason should be . However Bmw manufacturer may have a different definition for the P2146 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.

P2146 2005 2005 Bmw 428i Xdrive Code Clear

A good ground connection is also extremely important. P2146 2005 2005 Bmw 428i Xdrive engine problem because the presence of voltage at the panel harness won't make the panel work if there is a bad ground connection. Since the instrument cluster is mounted in a plastic dash, a separate ground wire or ground circuit through the wiring harness is usually needed to complete the power circuit. Refer again to the wiring diagram to find the ground path, and then check it with your ohmmeter. Do not use a self-powered test light because it cannot measure resistance (any resistance will lower circuit voltage).

2005 Bmw 428i Xdrive P2146 OBD-II Diagnostic Powertrain (P) Trouble Code Description

P2146 Fuel Injector Group A Supply Voltage Circuit/Open so you have to check ODB-II Fault Code Check list.

Reason For 2005 Bmw 428i Xdrive P2146 Code

The reason of 2005 Bmw 428i Xdrive P2146 OBD-II Fault Code Check is P2146 Fuel Injector Group A Supply Voltage Circuit/Open.
P2146 Code Reason


2005 Bmw 428i Xdrive P2146 Possibble Fix Ways :

Probably the biggest result of injector failure is due to the injectors having excessive return flow or back leakage. This is due to worn parts which allow excessive fuel to go through the diesel injector and to return back to the tank or fuel system. This causes a drop in rail pressure which results in hard starting or not starting at all.

OBD P2146 2005 2005 Bmw 428i Xdrive 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 P2146, 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 P2146 2005 2005 Bmw 428i Xdrive 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 P2146 2005 2005 Bmw 428i Xdrive 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.
