Error Code P0246: What It Means & What To Do?

<<See All OBD Codes

The wastegate is a turbocharged vehicle which is the part of the system which would regulate the maximum boost pressure by opening as well as closing so that it can divert exhaust. It would act as a protection for the turbocharger as well as the engine.

Now if this code is set by a vehicle, then it would mean that a signal has been received by the engine control module which would indicate that the wastegate solenoid A circuit voltage does not fall within the recommended specifications. There can be some other turbocharger or the engine codes which can get stored along with the P0246 error code.

The P0246 fault code can be described as Turbocharger Wastegate Solenoid High.

The wastegate solenoid would allow unneeded boost which has been generated by the turbo or the supercharger to vent the system. The wastegate solenoid is controlled by the ECM, it will set P0246 code. The PCM might also disable the turbo or the supercharger to prevent further damage to the system.

What causes this problem with the Turbocharger Wastegate Solenoid High?

• The wastegate solenoid might be bad
• A stuck or impaired wastegate door
• There can be a short or open in the solenoid harness
• The solenoid connectors can be corroded
• Some faults in the engine control module

1. Engine Control Module - Did your mechanic just found out that there is some fault in the Engine Control Module? Buy top notch Engine Control Module from us at economical prices.
2. Knock Sensor - A broken Knock Sensor can cause a lot of issues. It would be nice if you get it replaced on time.
3. Indicator Lamp - Everything is fine with the engine control module and still OBD code P0246 flashing? Then there is definitely some fault with the Indicator Lamp. Get it checked and replace if needed.
4. Wastegate Solenoid - Wastegate Solenoid is an important car part which should never be neglected. May be there is some fault in it due to which P0246 code may start flashing.

We care for our customers and that’s why we can totally understand your problem. That’s the reason why we have listed out some major symptoms behind the flashing up of OBD Code P0246. They are mentioned here as follows:

Common Symptoms

• A malfunction in the wastegate solenoid circuit
• There can be poor acceleration
• Abnormal sounds from the turbocharger or pipes
• Smoke coming out from the exhaust
• There can be poor engine performance
• The engine may experience a boost condition while idling, which could cause stalling or rough idling
• An illumination in the malfunction indicator lamp

We have listed out some ways which would help you to correct the OBD P0246

• The damaged wiring or connections to the wastegate solenoid should be repaired properly
• You can always replace the faulty solenoid
• Replace the engine control module

Now are you thinking that from where will you purchase these car parts? You have arrived at the right place. We at Parts Avatar care for our customers, that’s why we provide best quality of turbo boost, transmission slipping, electric turbo and boost controller at marketable prices.

Here are some steps which you should follow in order to diagnose this fault code:

• A scanner to the vehicle should be connect to check for other codes and to record freeze frame data
• Then you must clear the codes and then road test the vehicle to check if the code returns
• Address any co-existing DTCs in the order in which they occurred
• It is very important to visually inspect the wastegate solenoid and its surrounding circuitry and connections
• Examine the resistance and voltage to be sure they match manufacturer’s specifications
• The vacuum lines should be checked and wastegate door for sticking
• The wastegate door should be visually observed and actuator rod while the vacuum pump is being activated

Common Mistakes When Diagnosing The P0246 Code

The most common diagnostic errors may include replacing the wastegate solenoid without actually inspecting the rest of the system, such as the wastegate door and linkage. If the wastegate door is stuck, or connectors or wiring are compromised, replacing the solenoid may only result in continued failure

It is also very important not to overlook any boost pressure sensor codes that are present along with P0246. If one is present, this should be repaired first before the wastegate solenoid A circuit is repaired
