- Driving with a failed sensor is not recommended as the vehicle may stall or fail to restart.
Is Your Cadillac CT4's Camshaft Position Sensor Failing?
The camshaft position sensor in your 2022-2024 Cadillac CT4 is essential for engine health. It works with the crankshaft sensor to make sure your engine runs smoothly. When it starts to fail, your car's computer gets confusing information, which can cause noticeable problems. Ignoring these signs can lead to poor performance, bad fuel economy, and potentially leave you stranded.
Common Symptoms of a Bad Camshaft Position Sensor
A failing camshaft position sensor will almost always trigger the Check Engine Light. If you have an OBD-II scanner, you might see codes like P0340 or P0341. Beyond the light, you might experience:
- Hard Starting or No Start: The engine cranks but struggles to fire up, or won't start at all.
- Rough Idling and Stalling: The car may shake at a stop or shut off unexpectedly.
- Loss of Power: Your CT4 may feel sluggish and hesitate during acceleration.
- Reduced Fuel Economy: If the engine timing is off, it will burn more fuel than necessary.
Known Issues for 2.7L Engines
While there are no direct recalls for this sensor, GM issued a Technical Service Bulletin (TSB #PIP5843A) for 2020-2022 CT4 models with the 2.7L L3B engine. This TSB addresses issues where the intake camshaft's sliding lobe pack could bind in cold weather, potentially causing related diagnostic codes and requiring camshaft actuator or camshaft replacement. If you have a 2.7L engine and experience these symptoms, especially in the cold 🎬 Watch: Common symptoms of a bad camshaft position sensor, it's worth noting this TSB.
Choosing the Right Aftermarket Sensor
When it comes to critical engine sensors, quality matters. While the OEM ACDelco part is always a safe choice, high-quality aftermarket brands can offer the same performance for a better price. For your CT4, it's best to avoid the cheapest options, as they are known to fail prematurely.
Here's a breakdown of the available brands:
- Tier 1 (High Quality): NGK and Standard Ignition (SMP) are widely regarded as producing OEM-quality sensors. They have a strong reputation for reliability and are often the manufacturer for the original factory parts. These are a solid choice for a dependable repair.
- Tier 2 (Good Quality): Walker Products presents itself as a manufacturer of precision-engineered sensors that meet or exceed OEM standards. They are a well-known aftermarket brand and a viable option.
- Tier 3 (Economy): Brands like Holstein and True Tech fall into the economy category. While the price is attractive, there is less data on their long-term reliability. Some forum users have reported issues with lower-tier sensor brands on other vehicles, leading to repeat repairs. These are best considered if budget is the absolute primary concern and you are prepared for the potential risk.
Pro Tip: For a critical sensor like this, spending a few extra dollars on a Tier 1 brand like NGK or Standard Ignition can save you the headache of replacing it again in the near future.

Frequently Asked Questions
Where is the camshaft position sensor located on the Cadillac CT4?
The camshaft position sensor is typically located on the engine's cylinder head or valve cover, near the top of the engine. The CT4's 2.0L and 2.7L engines have dual overhead cams (DOHC), so there may be multiple sensors (e.g., one for the intake cam and one for the exhaust cam). Always verify the correct sensor location for your specific engine before starting work.
Can I replace the camshaft position sensor myself?
Yes, this is a DIY-friendly repair for many people. The process usually involves disconnecting the battery, unplugging the electrical connector, and removing a single bolt holding the sensor in place. 🎬 Follow this easy 7-step guide to replace your sensor However, some vehicles may require a computer "relearn" procedure after the new sensor is installed, which might require a specialized scan tool.
What are the error codes for a bad camshaft position sensor?
The most common codes are P0340 (Camshaft Position Sensor 'A' Circuit Malfunction) and P0341 (Camshaft Position Sensor 'A' Circuit Range/Performance). Code P0340 indicates a problem with the sensor's circuit, while P0341 suggests the signal is out of the expected range or not properly timed with the crankshaft.
