P195B BMW Fault Code

Description:

Throttle Position (TP) Sensor Intermittent The TP sensor circuit is monitored by the PCM for sudden BMW TP rotation angle (or voltage) input change through the comprehensive component monitor (CCM). If during the last 80 warm-up cycles in key ON engine running the BMW PCM detects a TP rotation angle (or voltage) changes beyond the minimum or maximum calibrated limit, a continuous diagnostic trouble code (DTC) is stored. Poor continuity through the TP sensor connectors Poor continuity through the TP harness Intermittent open or short inside the TP sensor While accessing the TP V PID on the scan tool, lightly tap on the TP sensor or wiggle the TP sensor connector and harness.

P195B Code Symptoms :

There are currently two main types of cylinder deactivation used today, depending on the type of engine. P195B 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 P195B

P195B 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 P195B code ?

• Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
• Failures of clutch motion/travel sensors.
• Faulty front heated oxygen sensor
• Intake air leaks

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code P195B, so consult the manual to locate the brake fluid reservoir.

Bear in mind that a low fluid level can set code P195B on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
