On-board diagnostic (OBD) systems are designed to help mechanics and vehicle owners identify problems. An illuminated check engine light is often the first sign that a trouble code has been logged in this system. A scan tool or code reader must be connected to the OBD port to retrieve the specific code.

One of the error codes you may come across is the P0019 code. Read on to learn more about what sets this code and what it may mean for a vehicle.

What Does the P0019 Code Mean?

Diagnostic trouble code (DTC) P0019 stands for “Crankshaft Position – Camshaft Position Correlation Bank 2 Sensor ‘B’.”

This code is set when the vehicle’s primary computer (also referred to as the powertrain control module or PCM) perceives that the crankshaft and the bank 2 exhaust camshaft are out of sync.

Code P0019 is a generic powertrain code that may be triggered in various makes and models. Bank 2 refers to the part of the engine opposite the bank containing the #1 cylinder, while “B” refers to the exhaust camshaft.

The crankshaft and camshafts are connected by a timing chain or belt. The crankshaft position sensor (CKP) detects the position of the crankshaft and sends that information to the PCM. On the other hand, a camshaft position sensor (CMP) detects the position of each camshaft and relays that information to the PCM. The cam and crankshaft should always be timed accurately to prevent engine problems.

Vehicles that are prone to code p0019 include various models of Cadillac (especially Cadillac CTS), Chevrolet, Mercedes Benz, GMC, and Subaru.

Note: The definition of code P0019 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Possible Causes of the P0019 Code?

  • Issues with the timing chain
  • Tone ring on crankshaft slipped/broken
  • Tone ring on camshaft slipped/broken
  • Faulty crank/cam sensor
  • Circuit issues (damaged wires or poor connections)
  • Worn or damaged timing belt/chain tensioner or guides
  • Failed VVT actuator solenoid
  • Faulty VVT actuator
  • Low oil level
  • Faulty PCM

What are the Common Symptoms of the P0019 Code?

Other DTCs may also be stored along with code P0019. Symptoms may vary if related codes like P0008, P0009, P0016, P0017, and P0018 are also set.

  • Check engine light is illuminated
  • Poor engine performance
  • Engine cranks but won’t start
  • Higher fuel consumption

How to Diagnose the P0019 Code

To ensure optimal engine performance, a code P0019 should be resolved immediately. However, diagnosing it can be tricky because it has many potential triggers.

Keep in mind that the steps for diagnosis and repair will vary depending on the specifications of your vehicle. A Cadillac P0019 code may require a different repair method from that of a P0019 on a Dodge.

Always consult your repair manual for diagnostic strategies. If you’re not well-versed in auto repair, it would be best to bring your vehicle to a mechanic.

How to Fix the P0019 Code

Vehicles that have logged code P0019 may exhibit similar symptoms associated with other engine codes. Therefore, having vehicle-specific repair information is critical to avoiding misdiagnosis. In most cases, it’s best to rely on the expertise of a mechanic to get your vehicle fixed.

If you plan on troubleshooting this code yourself, consult the vehicle’s repair manual or an online repair database for factory repair information. These recommended online resources may also help give you an idea of what the proper diagnostic procedure for this code might involve.
