OBD-II Code P0368: What It Is, Symptoms, Causes & How to Fix It with iCarsoft CR Ultra P
If your check engine light flashes on and a scan reveals OBD-II Code P0368—defined as “Camshaft Position Sensor ‘B’ Circuit High”—you’re dealing with a critical engine timing issue that can derail performance and even prevent your car from starting. The camshaft position sensor (CPS) is the “brain” of your engine’s timing, and a high-circuit fault means it’s sending faulty signals to the Engine Control Module (ECM). But you don’t need to overpay for dealer diagnostics: this guide breaks down everything you need to know about P0368, 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 P0368?
OBD-II codes are universal alerts from your vehicle’s ECM when powertrain malfunctions occur. Specifically, P0368 indicates a “high” voltage issue in the Camshaft Position Sensor ‘B’ circuit—the electrical path connecting the sensor (labeled ‘B,’ typically for the secondary camshaft on dual-cam engines) to the ECM.
The camshaft position sensor monitors the camshaft’s rotation, telling the ECM when to fire spark plugs and inject fuel. A “high circuit” means the ECM detects voltage above the acceptable range, usually from a shorted sensor, damaged wiring, or faulty connections. This miscommunication disrupts engine timing, leading to poor performance or stalling.
Common Symptoms of P0368
Don’t ignore these red flags—P0368 often manifests with these noticeable issues:
-
Illuminated or flashing Check Engine Light (flashing signals severe timing issues)
-
Difficulty starting the engine (or failure to start entirely)
-
Rough idling or engine shaking
-
Reduced power and sluggish acceleration
-
Increased fuel consumption (timing inefficiency wastes fuel)
-
Engine stalling at low speeds or under load
-
Poor engine performance (hesitation, bogging down)
-
Failed emissions tests (timing issues skew exhaust readings)
Top Causes of P0368
Pinpointing the root cause of P0368 is critical to avoiding further engine damage—and a professional diagnostic tool simplifies this. Common triggers include:
-
Faulty Camshaft Position Sensor ‘B’ (internal electrical failure)
-
Damaged, frayed, or shorted wiring in the CPS ‘B’ circuit
-
Loose, corroded, or water-damaged electrical connectors for the sensor
-
Malfunctioning ECM (rare, but possible if wiring and sensor check out)
-
Low battery voltage or faulty alternator (interrupts circuit power)
-
Oil contamination (leaking oil damages the sensor’s electrical components)
-
Incorrect sensor installation (loose mounting or misalignment)
-
Broken sensor reluctor ring (the toothed wheel that triggers the sensor)

Real Customer Reviews: iCarsoft CR Ultra P for P0368
“My 2018 Honda Accord threw P0368 and wouldn’t start after work. The dealer quoted $250 for diagnostics plus $400 for a new sensor! Bought the iCarsoft CR Ultra P, scanned it in 2 minutes, and it showed a shorted wire in the CPS ‘B’ circuit. Fixed it with electrical tape for $3, cleared the code, and my Accord started right up. Saved $600—this tool is a lifesaver!”
— Emily K., Ohio
“I’m a DIYer who struggled with P0368 on my Ford F-150. Cheap scanners only said ‘camshaft sensor issue’—no details. The iCarsoft CR Ultra P told me exactly which sensor (‘B’) was faulty and showed high voltage readings. Replaced the sensor for $70, cleared the code, and my truck’s power is back to normal. Super easy to use, even for someone new to engine timing!”
— Michael T., Texas
“Had P0368 on my Volkswagen Golf for weeks. Local shops couldn’t decide if it was the sensor or ECM (a $1,200 fix!). The iCarsoft CR Ultra P’s live data showed the sensor was working, but the connector was corroded. Cleaned it, cleared the code, and the Check Engine Light stayed off. This tool saved me from a huge scam—highly recommend for timing issues!”
— Sophia M., Colorado
FAQ: Everything You Need to Know About P0368 & iCarsoft CR Ultra P
What exactly does OBD-II Code P0368 mean?
P0368 indicates a high-voltage fault in the Camshaft Position Sensor ‘B’ circuit—disrupting engine timing and sending faulty signals to the ECM.
Is it safe to drive with P0368?
No—P0368 can cause stalling, reduced power, or complete engine failure. Avoid driving long distances and fix it promptly to prevent costly engine damage.
Can I clear P0368 without a diagnostic tool?
Disconnecting the battery resets the Check Engine Light temporarily, but P0368 will return unless you fix the sensor, wiring, or connectors. 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?
