P0075 code definition

Intake Valve Control Solenoid Circuit (Bank 1)

What does the P0075 code mean?

The P0075 code varies by manufacturer, but it is a general powertrain trouble code for 1996 and newer cars with Variable Valve Timing (VVT) operating normally with oil pressure and controlled by the camshaft position solenoid on engine bank 1 (located on engine side with cylinder #1). This code is related to the solenoid and electrical circuit.

What causes the P0075 code?

  • Wiring harness poor connection or damaged connectors
  • A faulty control solenoid
  • A short to the power side
  • A short to ground
  • The Engine Control Module (ECM) is faulty

What are some of the symptoms of P0075 code?

A faulty intake valve control can cause the engine intake valves to not change the lift to them and will cause an engine imbalance from bank to bank, causing the engine to run rough, hesitate, surge and possibly stall. The Check Engine Light would then come on once the ECM detects the failure in the intake valve control circuit.

How does a mechanic diagnose the P0075 code?

  • Looks for the Check Engine Light which may illuminate

  • Verifies the P0075 code with an OBD-II scanner

  • Resets all fault codes and performs a road test to see if the P0075 code returns

If the code returns, follow the mechanic should follow the test procedure:

  • Check the wiring harness for any unplugged/loose connections, corrosion, or any other damage

  • Verify that the wires have less than one ohm resistance (more than one ohm could mean damaged or grounded wires)

  • Check the intake valve control solenoid itself for damage

Common mistakes when diagnosing the P0075 code

Do not assume the solenoid is defective. The wiring is often the cause of this code, but the solenoid can also be damaged, which typically happens during maintenance work on the engine. It is very important to do a careful inspection of the entire circuit before replacing the solenoid.

How serious is the P0075 code?

The code is preceded by the engine warning light coming on the instrument panel. Often this condition causes erratic engine operation, poor acceleration and excessive fuel consumption under load. This situation requires attention and diagnosis as soon as possible to prevent further engine problems and damage.

What repairs can fix the P0075 code?

Because this code P0075 is different for each manufacturer, it is best to follow the specific instructions from that manufacturer before replacing any components. Many tests simply do not apply to all vehicles and the function and operation of individual components.

Many cars now use Variable Valve Timing to improve performance and fuel economy. The methodologies are often different due to patent rights and manufacturer processes using a variety of power sources, such as electricity, oil pressure, and engine rpm to operate. Most European cars have had these systems for years and each are different, adding to the complexity of the operation. BMW has at least 4 different evolutions as they have been a leader in this technology. The test procedure here is very general, but applies to most cars with the system.

It is very advisable to follow the manufacturer instructions for each model of vehicle to make sure the procedure is done precisely.

Additional comments for consideration regarding the P0075 code

Many vehicles with mileage over 100,000 have momentary sensor problems that usually occur during start up or prolonged stress situations on the drive train.

If the engine warning light comes on and the vehicle seems to be operating normally, the OBD-II system can be reset using the scanner and the problem may not reoccur. This is why it is important to verify the fault and reset it before doing any repairs.

Your Mechanic is brilliant! This is my first time using the service and I absolutely love it. Great service, convenient, and reasonable rates. I will definitely recommend to all of my friends and family. Honorio came out to my workplace and worked on my car. He arrived timely and was very efficient and knowledgeable. He tightened some parts that were loose, which made my service engine light turn off! :) He took pictures and gave me a detailed breakdown of repairs my car would need in the near future. Honorio was very confident, experienced, and genuine. I give him 5+ stars! Thanks Honorio!
