P225B 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.

P225B Code Symptoms :

When you turn on the ignition, the Service Engine Soon or Check Engine P225B light should flash briefly, indicating that the OBD system is ready to scan your vehicle for any malfunctions. After this brief flash, the light should stay off while you drive as long as no problems are detected. If so, you'll be glad to know that your vehicle is equipped with an early warning system that could save you time, money, and fuel in addition to helping protect the P225B!

Diagnosis And Repairing P225B

P225B 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 P225B code ?

• Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
• Faulty Camshaft Position Sensor
• Continuous oil flow to the VCT piston chamber

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code P225B, so consult the manual to locate the brake fluid reservoir.

Bear in mind that a low fluid level can set code P225B on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
