Toyota Camry P0368: Misfire Detected - Fuel Disabled (P0368) diagnosis
Code verification standard
P0368 is published with SAE J2012 / ISO 15031-6 code structure plus Toyota Camry diagnostic context.
This page covers meaning, symptoms, first checks, live data, misdiagnosis risk, and repair verification.
What does this mean?
P0368 means Misfire Detected - Fuel Disabled (P0368). Treat it as a diagnostic starting point, not a parts order. Confirm the fault with freeze-frame data, related codes, wiring and connector checks, live data for the misfire system, and a repair verification drive cycle before replacing expensive components.
How serious is this code?
P0368 may be drivable if the vehicle runs normally, but stop driving if the warning light flashes, the engine overheats, power drops sharply, shifting becomes unsafe, or fuel/exhaust smells are strong.
Diagnostic system: Misfire and combustion
On a Toyota Camry, the P0368 code should be diagnosed as part of the misfire and combustion group. Related codes and live data from this same system can change the repair priority, so avoid replacing parts from the code name alone.
Most Common Causes for Toyota Camry
- Worn or fouled spark plugs
- Faulty ignition coil or coil pack
- Clogged or faulty fuel injector
- Vacuum leak in intake system
- Blown head gasket
Symptoms to Watch For
- Check Engine Light is illuminated
- Engine misfiring or shaking sensation
- Rough or unstable idle
- Significant loss of engine power
- Vehicle enters reduced power / limp mode
- Unusual vibration during driving
- Failed emissions test
Before replacing parts, check these first
- Check spark plugs, coils, injector balance, and compression before replacing expensive parts.
- Review freeze-frame RPM/load to see when the misfire occurs.
- Look for fuel trim or vacuum leak codes that can cause multiple-cylinder misfires.
- Check for blown fuses, weak battery voltage, and damaged connectors before buying major parts.
Live data to compare
- Mode $06 misfire counters
- Fuel trim at idle and cruise
- Coil/injector swap result and compression reading
How to Diagnose
Common Mistakes
Replacing ignition coils without moving coils, checking plugs, or confirming fuel and compression are healthy. Always confirm the fault with freeze-frame data, live data, visual inspection, and circuit checks before spending money on parts.
Repair verification
After the repair, clear P0368, complete a drive cycle, and confirm the monitor runs without the code returning. Save the before/after scan report if the vehicle needs emissions inspection.
Frequently Asked Questions
Can I drive with the P0368 code?
If the check engine light is solid, you can usually drive to a safe location or mechanic. If the light is flashing, pull over immediately to prevent catastrophic engine or catalytic converter damage.
Will the P0368 code clear itself?
Once the underlying problem is fixed, the engine computer will run its self-checks. If it passes over several drive cycles, the light will turn off automatically. You can also clear it immediately using an OBD2 scanner.
Will this code fail an emissions test?
Yes. If the Check Engine Light is on due to the P0368 code, your Toyota will automatically fail an OBD2 plug-in emissions or smog test.
What should I check first for P0368?
Check spark plugs, coils, injector balance, and compression before replacing expensive parts. Review freeze-frame RPM/load to see when the misfire occurs. Look for fuel trim or vacuum leak codes that can cause multiple-cylinder misfires.

Repair Estimate
Spark plug, coil swap test, or connector repair
Major component replacement after live data and circuit tests confirm failure
Includes parts and labor. May vary by location.
Single-cylinder ignition fixes are often affordable; compression or timing problems require professional diagnosis.
DIY Difficulty
Can usually be performed at home with basic hand tools.
