Guide To P0076 OBD Error Code Solutions

<<See All OBD Codes

The P0076 OBD code can be defined as an Intake Valve Control Solenoid Circuit Low. The position of the exhaust valve is controlled by the Intake Valve Control Solenoid as it uses oil pressure and an electrical solenoid. The vehicles which are new are well equipped with variable valve timing or the VVT. The opening as well as closing of the exhaust valve is adjusted by the engine control module so that it can improve the overall fuel consumption at the same time keeping in mind to provide the performance requested by the driver. Whenever the PCM would determine that there is some problem with the signal from the Intake Valve Control Solenoid, then the code P0076 code would set.

P0076 is an OBD2 error code which would start appearing when there is some issue with the Bank 1 intake valve control solenoid circuit. This would mean that the car computer or the engine control module has detected a sensor which might be out of specified voltage range.

What causes this problem with the Intake Valve Control Solenoid Circuit Low?

• Poor connection or corroded terminals in the wire harness
• There can be some defects in the control solenoid
• Problem of short to power
• The issue of short to ground
• Faults in the engine control module
• Defects in the intake valve control solenoid bank
• 1 Intake Valve Control Solenoid Circuit Bank 1 harness may be opened or shorted

1. Boost Pressure Sensor - The P0076 code can also arise due to some issues in Boost pressure sensor. So, it is advised to replace them as soon as possible.
2. Turbocharger - There can be some issues with the Turbocharger due to which you may see P0076 code appearing over and over again. Visit us to buy best quality Turbocharger online.
3. Supercharger - The P0076 code can also arise due to some issues in Supercharger. So it is advised to replace them as soon as possible.
4. Knock Sensor - Are you facing OBD Error Code P0076? Don’t worry as you can fix this issue with new Knock sensor. We care for our customers, that’s why we have Knock sensor for every make and model.
5. Spark Plug - A broken Spark Plug can cause a lot of issues. It would be nice if you get it replaced on time.
6. Intake Manifold - Do you remember when was the last time you got your car Intake manifold checked up? A damaged Intake manifold can cause a lot of issues like displaying P0076 code.
7. Boost Pressure Gauge - Boost Pressure Gauge is an important auto part. Take care of it and you can rely on us to purchase best quality Boost Pressure Gauge online.
8. Powertrain Control Module - Damaged PCM hampers the engine timing. Find all the Powertrain related parts with us.
9. Engine Control Module - OBD Error Code P0076 can also be due to faulty ECMs. It’s better to get the faulty electricals replaced as soon as possible.
10. Wastegate - OBD Error Code P0076 can simply be due to faulty Wastegate. Replace old and damaged components now!

Willing to know some common symptoms of OBD Code P0076? Your wish is our demand. Have a look at them below:

Common Symptoms

Some sort of faults in the intake valve control can cause the engine intake valves to not change the lift to them and will ultimately lead to an engine imbalance from bank to bank, which would cause the engine to run rough, hesitate, surge and possibly stall. The check engine light will start illuminating on once the engine control module detects the failure in the intake valve control circuit.

• This error code would start appearing because there can be some problem which is existing somewhere within this circuit preventing proper boost control. Additional codes in progression may be set regarding this malfunction, each of which pertains to a section of the circuit
• There can be lack engine acceleration
• The boost pressure gauge may start indicating less than 9 pounds of boost or it can exceed over 14 pounds of boost. Both of them would be out of range
• There can be unusual whining noises or rattling which may be coming from the turbocharger or piping
• Engine knock sensor code may start appearing indicating detonation is occurring due to high cylinder head temperatures
• There can be an overall lack of power in the car engine
• Smoke may start emitting out from the exhaust
• There spark plugs can be fouled
• Engine temperature may become unusually high at cruise speeds
• There can be some hissing noises at the waste gate

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of aem intake, shift solenoid, airaid intake, engine manifold and a lot more. We are sure that now all your issues would be resolved.

The electrical solenoids as well as the oil pressure are used by the Intake Valve Control Solenoid to control the position of the exhaust valve. The vehicles which are new are well equipped with variable valve timing. It would allow the engine control module to adjust the opening as well as closing of the exhaust valve, thus improving the overall fuel consumption and at the same time would provide the performance which is requested by the car driver. If the power control module determines that there is some sort of issue with the signal coming from the intake valve control solenoid, then the powertrain control module would set the P0076 code.

• The overall engine performance may start decreasing
• The car engine may not start properly
• There can be an increase in the fuel consumption

Common Mistakes When Diagnosing the P0076 Code

Make sure that you do not assume that the solenoid is defective. There can be some issue with the car wiring which can be a reason why P0076 trouble code is triggering up. There are chances that the solenoid may be damaged during the maintenance work being done on the car engine. Carefully check the entire car circuit before you start replacing the solenoid.
