P0019 – Meaning, Causes, Symptoms, & Fixes

Code P0019 Definition

The correlation of the camshaft and crankshaft positions on bank 2 is incorrect based on the exhaust camshaft position sensor.

What Does P0019 Mean?

In order for the engine to run smoothly and efficiently, it has to know exactly where the camshaft and crankshaft is in its rotation. It does this by monitoring them using the Camshaft Position Sensors and Crankshaft Position Sensor. If the Engine Control Module (ECM) detects that the bank 2 exhaust camshaft and crankshaft are not in the correct position, it will trigger code P0019.

What Are The Symptoms Of Code P0019?*

  • Check Engine Light
  • Rough running engine
  • Poor fuel economy
  • Decreased engine performance
  • Timing chain noise
  • Hard/extended start
  • No start

*No noticeable adverse conditions in some cases

What Is The Cause Of Code P0019?

  • Stretched timing chain
  • Jumped timing
  • Slipped reluctor ring on the crankshaft
  • Slipped reluctor ring on bank 2 exhaust camshaft
  • Faulty timing chain tensioner
  • Low/dirty oil

How Serious Is Code P0019? – Severe

This trouble code can cause the vehicle to be hard to start and run rough. In some cases, the vehicle may not be driveable. It should be addressed as soon as possible.

Code P0019 Common Diagnosis Mistakes

Not checking for TSBs before starting diagnosis

Tools Needed to Diagnose:

  • FIXD
  • Basic Hand Tools
  • Vehicle Specific Service Manual
  • Oscilloscope

How To Diagnose And Repair Code P0019?

Difficulty of Diagnosis and Repair (5 out of 5)

  1. Check to see if there are any other codes along with P0019 and clear your Check Engine Light with FIXD.
  2. Check the freeze frame data in order to pinpoint the issue.
  3. Check for any Technical Service Bulletins (TSB) General Motor vehicles (GMC, Chevrolet, Buick, Suzuki, Cadillac, Holden) specifically have a known issue with stretched timing chains. If your vehicle applies to a TSB, perform this first.
  4. Check oil level and if incorrect, correct to the proper level. If it’s dirty, replace the engine oil and filter and see if the code comes back.
  5. This code requires an oscilloscope for proper diagnosis. Not all shops are equipped with this but many are. Using the O-scope (oscilloscope), you would connect to the signal wire for the crankshaft position sensor and bank 1 and bank 2 camshaft position sensors and compare the three to each other. If they are offset from their proper locations, a stretched timing chain, jumped timing or slipped reluctor ring is the issue. Replace the necessary parts to resolve the concern. Below is an image of what this test should look like on an O-scope screen.

Estimated Cost of Repair

For error code P0019, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair.

  • Timing chain $600-$1200
  • Reluctor ring $200-$600
  • Engine oil and filter change $20-$60

  1. Before I got the Fixed sensor for my 2005 Buick Lacrosse, I replaced the sparkplugs, plugwires, ignition coils, ICM, MAP sensor, oil sending unit, water pump, transmission filter & fluid. The Fixed sensor cannot or won’t tell me why the oil can & 🔧 light is on or what it means.

  2. I have two cars on my first car I checked it and got my codes I had to put in my VIN number and everything but on my second car I didn’t see or it didn’t ask me to put in a VIN number or anything so I’m wondering if it’s giving me the reading from the first car when I checked the second one

  3. All instruments panel stop working on my Volvo 2004 s80

  4. I did everything I suppose to and it still doesn’t come in.

  5. Having problems with fuel gage says it full and ran out gas so checking the system will not diagnose it … if the sensor at fuel pump is going ????

  6. My 2008 Chevy Equinox LT is having an evaporative air problem. Also many of the panel lights are always on Does this get resolved by fixing or replacing the EGR valve?

  7. Is there any possibility a PO code 505 and PO Code 325 … could that confuse the e c m and cause the vehicle to have “NO REVERSE” when PUT IN reverse selection, in the transmission?it’s automatic transmission . ….. ?

  8. Which steps can I follow to reduce TAC volts i on 2AZ-FE

  9. Hi my codes are P0306, P0340 what do they mean

    1. Carolin, sounds like you’ve got a cylinder 6 misfire and Camshaft Position Sensor Circuit Malfunction. Please check out these posts for more info on your codes:
