P296F BMW Fault Code

Description:

BMW Mass Air Flow (MAF) Sensor Intermittent The MAF sensor circuit is monitored by the PCM for sudden voltage (or air flow) input change through the comprehensive component monitor (CCM).

If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory diagnostic trouble code (DTC) is stored.

P296F Code Symptoms :

There are currently two main types of cylinder deactivation used today, depending on the type of engine. P296F code for the pushrod design which uses solenoids to alter the oil pressure delivered to the lifters. In their collapsed state, the lifters are unable to elevate their companion pushrods under the valve rocker arms, resulting in valves that cannot be actuated and remain closed.

Diagnosis And Repairing P296F

P296F OBD 2 code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission.

How to fix P296F code ?

• Failures of clutch motion/travel sensors.
• Failures of clutch motion/travel sensors.
• Continuous oil flow to the VCT piston chamber
• Incorrect fuel filler cap used

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code P296F, so consult the manual to locate the brake fluid reservoir.

Bear in mind that a low fluid level can set code P296F on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
