OBD-II Code P0269: What It Is, Symptoms, Causes & How to Fix It with iCarsoft CR Ultra P
If your engine shakes violently, loses power, or triggers the check engine light with OBD-II Code P0269—defined as “Cylinder 3 Contribution/Balance Fault”—you’re facing a cylinder-specific performance issue. Cylinder 3 is failing to contribute its share of power to the engine, disrupting balance and risking long-term damage. But you don’t need to overpay for dealer diagnostics: this guide breaks down everything you need to know about P0269, plus why the iCarsoft CR Ultra P diagnostic tool is the DIYer’s must-have to detect, troubleshoot, and clear this error code for good.
What Is OBD-II Code P0269?
OBD-II codes are universal alerts from your vehicle’s Engine Control Module (ECM) when powertrain systems malfunction. Specifically, P0269 indicates Cylinder 3 is not contributing properly to engine power—meaning its combustion efficiency is far lower than the other cylinders.
The ECM monitors each cylinder’s performance via crankshaft speed fluctuations: when Cylinder 3 misfires, has weak combustion, or fails to fire entirely, it creates an imbalance in engine rotation. This “contribution fault” undermines power delivery, increases wear on other cylinders, and can lead to costly engine damage if left unaddressed. Cylinder 3’s location varies by engine (inline engines: 3rd from the front; V-shaped engines: Bank 1 or 2, depending on make/model).
Common Symptoms of P0269
Watch for these telltale signs that P0269 is affecting Cylinder 3:
-
Illuminated or flashing Check Engine Light (MIL)
-
Severe engine vibration at idle or low speeds
-
Reduced power and sluggish acceleration (Cylinder 3 isn’t pulling its weight)
-
Increased fuel consumption (other cylinders compensate for Cylinder 3’s failure)
-
Engine misfires (audible popping or sputtering from the engine bay)
-
Rough idling that may lead to stalling
-
Black smoke from the exhaust (unburned fuel from Cylinder 3)
-
Failed emissions tests (incomplete combustion skews exhaust readings)
Top Causes of P0269
Pinpointing the root cause of P0269 (specific to Cylinder 3) is key to targeted repairs—and a professional diagnostic tool simplifies this. Common triggers include:
-
Faulty or clogged fuel injector (Cylinder 3): Delivers insufficient or uneven fuel
-
Damaged ignition coil or spark plug (Cylinder 3): Weak or no spark for combustion
-
Low compression in Cylinder 3: Worn piston rings, damaged valves, or head gasket leak
-
Intake air leak (near Cylinder 3’s intake manifold): Disrupts air-fuel mixture
-
Malfunctioning oxygen (O2) sensor (upstream, near Cylinder 3): Sends incorrect data to the ECM
-
Fuel pressure issues: Faulty pump or regulator – inconsistent fuel delivery to Cylinder 3
-
Vacuum leaks: Damaged hoses or gaskets – affects Cylinder 3’s air intake
-
ECM software glitch or malfunction: Rare, but possible if other components check out

Real Customer Reviews: iCarsoft CR Ultra P for P0269
“My 2017 Ford F-150 threw P0269 and shook like a washing machine. The dealer quoted $400 for diagnostics plus $800 for new injectors! Bought the iCarsoft CR Ultra P, scanned it in 2 minutes, and it showed Cylinder 3’s ignition coil was faulty. Replaced it for $50, cleared the code, and my truck runs smooth again. Saved $1,150—this tool is invaluable!”
— Chris M., Texas
“I’m a DIYer with a Toyota Corolla that had P0269. Cheap scanners only said ‘cylinder misfire’—no cylinder info. The iCarsoft CR Ultra P pointed directly to Cylinder 3’s clogged injector. Cleaned it with injector cleaner for $12, cleared the code, and the vibration stopped. Super easy to use, even for someone new to cylinder-specific issues!”
— Emma K., California
“Had P0269 on my Volkswagen Jetta for weeks—dealer wanted $1,200 to rebuild the engine (said low compression). The iCarsoft CR Ultra P’s live data showed a vacuum leak near Cylinder 3, not compression issues. Fixed the cracked hose for $18, cleared the code, and power is back. This tool saved me from a disaster—highly recommend!”
— Liam T., Florida
FAQ: Everything You Need to Know About P0269 & iCarsoft CR Ultra P
What exactly does OBD-II Code P0269 mean?
P0269 indicates Cylinder 3 is not contributing properly to engine power—causing imbalance, vibration, and reduced performance.
Is it safe to drive with P0269?
It’s not ideal: continued driving can damage other cylinders, the catalytic converter, or the crankshaft. Fix it promptly to avoid costly repairs.
Can I clear P0269 without a diagnostic tool?
Disconnecting the battery resets the Check Engine Light temporarily, but Cylinder 3’s fault remains. A tool like the iCarsoft CR Ultra P is needed to identify the root cause.
Will the iCarsoft CR Ultra P work with my vehicle?
It’s compatible with most OBD-II compliant vehicles (1996+ US, 2000+ EU/Asian) including cars, trucks, SUVs, and vans. Check the product page for full brand/model coverage.
Do I need technical skills to use it?
No! It’s plug-and-play: connect to your vehicle’s OBD-II port (under the dashboard), turn on the ignition, and follow on-screen prompts to scan for P0269.
Will the iCarsoft CR Ultra P clear P0269 permanently?
Yes—if you repair the root cause (e.g., replace coil/injector, fix leak). The tool resets the ECM, so the code won’t return if Cylinder 3 contributes normally.
How much money can I save with this tool?
Professional diagnostics for P0269 cost $150–$400, plus $300–$1,500 in repair fees. The iCarsoft CR Ultra P pays for itself after one use.
