Guide To P226B OBD Error Code Solutions

<<See All OBD Codes

The trouble code P226B can be explained as Turbocharger/Supercharger Boost Pressure Too High – Mechanical. The electronic turbo actuator electronically activates the variable geometry turbocharger (VGT). It is a smart device which receives information via the CAN BUS from the engine control module. The electronic turbo actuator makes sure to perform its own diagnostics and would report failure back to the ECM using the CAN BUS. Then the error messages would be decoded by the ECM. Later it would convert it into an error code.

This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Turbocharger/Supercharger Boost Pressure Too High – Mechanical?

• Some issues related to the engine control module calibration update
• There might be soot build up on turbocharger
• Malfunctioning turbocharger

1. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have best auto parts for our customers.
2. Fuel Tank Pressure Sensor - The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It is part of the evaporative emissions system and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap. Replace faulty pressure sensor now!
3. Powertrain Control Module - The on-board computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
4. Fuel Sender Connector - Always check for faulty sender connectors as they can hinder the fuel delivery system, leading to lean or rich engine conditions, causing performance issues. Thus, replace faulty fuel sender connectors now!
5. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.
6. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P226B error with the help of experienced mechanic. Visit us today!

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P226B code to be stored:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the turbocharger/supercharger boost pressure itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
• On test driving, if the P226B code does not return soon, he will know that an erratic condition exits.
• But if the error returns instantaneously, he will check every components of the control module as well as the circuit like connectors, wires, harness, fuses etc. for any possible fault.
• If any component is damaged, he will fix them right away.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.

Common Mistakes When Diagnosing The P226B Code

• Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one doesn’t follow all the steps carefully
• The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
