What are the possible causes of a p0026 Subaru?

What are the possible causes of a p0026 Subaru?

P0026 SUBARU Possible Causes 1 Dirty engine oil 2 Low engine oil level 3 Faulty intake valve control solenoid 4 Intake valve control solenoid harness is open or shorted 5 Intake valve control solenoid circuit poor electrical connection

How to diagnose intake valve control solenoid circuit p0026?

NOTE: When diagnosing code P0026, start the procedure by inspecting the engine for oil leaks that could have reduced the engine oil level. Repair oil leaks as required, top off the oil level, clear the code, and operate the vehicle. Rescan to see if the code returns. If the code persists, proceed as follows-

What does the OBD II fault code p0026 mean?

What Does Code P0026 Mean? OBD II fault code P0026 is defined as “ Intake Valve Control Solenoid Circuit Range/Performance (Bank 1)”, with “Bank 1” denoting the side of the engine that contains cylinder #1 on engines with two cylinder heads.

Where is Bank 1 solenoid located on a Subaru Outback?

Each solenoid is paired with a pressure sensor — the vertical part with the white connector. The bank 1 solenoid is the one the passenger side at the rear. Even though the CEL has gone out (after three drive cycles), the code might still be stored in the memory.

Where is the p0028 code on a Subaru Outback?

Fruit Flies Like a Banana! Oil level and leaks around the variable valve lift solenoids or pressure sensor switches have been seen before as causes of the P0028 code, as has been noted above. The code is for bank 2. The related solenoid and switch are at the front of the left side head and easily checked for oil leaks.

What happens to the solenoid on a Subaru Outback?

If its low of oil, the solenoid operates but the cam doesn’t change and the pressure switch feedback doesn’t change. Since the ECM only sees voltage data and not mechanical, it sets a code for the solenoid circuit assuming that the oil is at the proper level and viscosity and the signal returned to it by the pressure switch is correct.

What causes two engine codes on a Subaru Outback?

If the resistance of the sensor contacts is too high, the ECM will interpret this as an “open” sensor when it should be closed. I believe this is a common cause of the two codes — deterioration of the sensor internal contacts.

What is the code for a 2006 Subaru Legacy?

My 2006 2.5 Legacy’s check engine light came on last week and the cruise light is flashing. When idling, the car vibrates sometime. I checked the code, and it is P0026 so I replaced the B1 intake valve control solenoid, oil pressure switch , changed oil then cleared the code.

Why do I get a code on my Subaru?

This too could cause the code, either immediately, or if it’s not a total blockage, perhaps only intermittently. This would need more testing; a scanner that can monitor the solenoid control signal and the on/off state of the switch could be used (dealers have the Subaru Select Monitor III for this).

What’s the resistance of a Subaru pressure switch?

While the “new” pressure switch resistance seems a bit low compared to reports others have provided, when the switch is “on”, that is, the internal contacts closed (this is the way it is when the engine is off), the lower the resistance the better. So 0.6 Ohms isn’t necessarily bad.

How much does it cost to diagnose a p0028 Subaru code?

The cost to diagnose the P0028 SUBARU code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. How much do you know about cars? When is the code detected?

What is the fault code on a Subaru Impreza?

In this video we discuss a common Subaru fault code associated with variable valve lift systems on the 2.5L engines. This code is common across 2006-2011 Subaru Foresters, Impreza, Outback and Legacy vehicles equipped with the 2.5L engine. P0026 and P0028 indicate a fault in the VVL circuit.
