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 causes a p0028 code on a valve lift?
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 when oil pressure is low on a Subaru Outback?
If its not low, then there may be an issue with the control solenoid, pressure switch or oil circulation for cam lift to take place. The VVL solenoid controls oil flow to change the camshaft lift. If its low of oil, the solenoid operates but the cam doesn’t change and the pressure switch feedback doesn’t change.
Where is Bank 1 and Bank 2 on a Subaru Outback?
In the USA, for the six cylinder H6 engine, Bank 1 is on the passenger side, Bank 2 is the driver side (left side as you sit in the car) Appears to be opposite of most other cars, and certainly confusing on this forum as to which is which! There are several reasons a P0420 will come up as an error and illuminate the MIL.

What is the p0026 code on a Subaru Legacy?
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. I drove 200 miles fine, but today the CEL came back on with flashing cruise light but no vibrations, the car drives smoothly.

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.
Where is the pressure switch on a Subaru Outback?
The related solenoid and switch are at the front of the left side head and easily checked for oil leaks. There’s photos in this post: http://www.subaruoutback.org/forums…il-pressure-switch-resistance.html#post473452
How much does it cost to diagnose Subaru code p0026?
The cost of diagnosing the P0026 SUBARU code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0026 SUBARU code detected?
What is the pressure sensor on a Subaru Outback?
You’ve identified the VVL solenoids correctly (1st photo, sloped, with the blue connector). Each solenoid is paired with a pressure sensor — the vertical part with the white connector.
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.
When to use the code p0028 on a VVT?
Code P0028 is set when the PCM (Powertrain Control Module) detects a fault in the electro-hydraulic control system of the VVT (Variable Valve Timing), or VCS (Variable Camshaft System).
How to diagnose intake valve control solenoid circuit p0028?
NOTE: When diagnosing code P0028, 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 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.
How long does the p0028 code stay in memory?
In this regard, if in the next three drive cycles no faults had been detected (e.g. if the P0028 was a single “event”), the CEL would have gone out on its own and the cruise control restored, while the trouble code itself would have remained in memory for up to 40 drive cycles. This might have been useful for the dealer.
What does a minor trouble code on a Subaru do?
On newer cars, even a ‘minor’ trouble code is programmed to disable cruise and traction control so, it isn’t unusual to have a CEL and 2-3 other lights on. I have had spurious codes set in both my soobs. One was related to a bad cell in the battery. The other is still a mystery.
