B0379 Peugeot Expert OBD Code

OBD/2 B0379 error code description and symptoms.

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code B0379

At this point we are assuming that the fuses and relays are good. You will need to locate the PCM/TCM and the power input signal circuit using your vehicle information source. Unplug the connector from the PCM/TCM, place the ignition switch in the ON position, and probe the appropriate circuit with the positive test lead of the DVOM.

B0379 Peugeot Expert Error Code Repair Process :

OBD B0379 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 shift solenoid b electrical/ 2-3 shift solenoid circuit electrical, 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 B0379 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 B0379 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.

Common Causes of Peugeot Expert B0379 OBD2 Code

A common cause of code B0379 is the failure of Shift Solenoid B Electrical/ 2-3 Shift Solenoid Circuit Electrical, but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Incorrect Positive Crankcase Ventilation (PCV) hose connection
Faulty Air fuel ratio (A/F) Sensor 1 Bank 1
