P0019: Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)

Quick Answer
Alta GravitàNon sicuro da guidareAccensione

P0019 means the crankshaft and the exhaust camshaft on bank 2 are not in the correct rotational relationship. The code only appears on V-engines (V6, V8, V10, V12) because bank 2 is the side that does not house cylinder 1. Common causes include a stretched timing chain, a failed exhaust VVT solenoid on bank 2, a worn camshaft phaser, or oil flow problems.

Cosa significa P0019?

P0019 means the crankshaft and the exhaust camshaft on bank 2 are not in the correct rotational relationship. The code only appears on V-engines (V6, V8, V10, V12) because bank 2 is the side that does not house cylinder 1. Common causes include a stretched timing chain, a failed exhaust VVT solenoid on bank 2, a worn camshaft phaser, or oil flow problems.

P0019 è un codice diagnostico di guasto relativo a accensione, classificato con gravità high. Quando la centralina (ECU) del tuo veicolo rileva questa condizione, memorizza P0019 e accende la spia motore.

Quali sono i sintomi di P0019?

Se il tuo veicolo ha attivato P0019, potresti notare uno o più di questi sintomi:

  • Check engine light illuminated
  • Loud rattle from the front of the engine at cold start
  • Rough idle and possible misfires on bank 2
  • Hard starting, particularly when warm
  • Noticeable loss of power and hesitation
  • Increased fuel consumption

Cosa causa P0019?

Ecco le cause più comuni di P0019, ordinate in base alla probabilità che siano la causa del problema:

altaStretched timing chain (chronic on Audi 3.0 TFSI, VW 3.0 TDI, Mercedes M276)
altaFailed bank 2 exhaust VVT solenoid
mediaLow or degraded engine oil restricting VVT operation
mediaWorn timing chain tensioner on bank 2
bassaFailed bank 2 exhaust camshaft phaser
bassaBank 2 exhaust camshaft position sensor fault

È sicuro guidare con P0019?

No, risolvi subito il problema. Drive only short distances to reach a workshop. P0019 indicates the exhaust camshaft on bank 2 is out of correlation with the crankshaft. On an interference V-engine, continued driving risks the chain skipping teeth and bending valves, which on a V6 or V8 means a 5000 EUR or greater engine rebuild.

Come si diagnostica P0019?

Segui questi passaggi per individuare la causa principale di P0019:

  1. Check engine oil level and condition. V-engines share oil between banks, so low pressure or contamination affects both. Use only the manufacturer-specified viscosity and approval (BMW LL-04, VW 504.00/507.00, MB 229.5/229.51)
  2. Listen for cold-start rattle from the front of the engine. On V6 and V8, the rattle may originate from one bank specifically. A stethoscope helps localise it
  3. Use a scan tool to monitor live cam phasing data on bank 2 exhaust. Compare actual versus commanded angle. Deviations over 5 to 10 degrees confirm mechanical timing fault
  4. Test the bank 2 exhaust VVT solenoid. Resistance typically 6 to 13 ohms. Inspect the mesh screen for sludge debris. A clogged screen is a common quick fix
  5. If the solenoid and oil are good, suspect timing chain stretch or guide wear on bank 2. A workshop will need to remove the bank 2 valve cover or front cover for inspection

P0019 su BMW 3 Series

2005–2024

P0019 on a 3 Series implies the M3 with the S65 V8 (E90/E92 era) or a sedan equipped with a V8. The S65 has known cylinder bank issues including VANOS solenoid failures on bank 2. Combined with the M3's rod bearing service requirement at 100,000 km, addressing P0019 is often bundled with preventive maintenance.

P0019 su Audi A6

2005–2024

The A6 3.0 TFSI EA837 supercharged V6 sets P0019 frequently around 100,000 to 150,000 km. The bank 2 exhaust camshaft adjuster is one of the most common failures in the EA837 family. Repair requires removing the supercharger. Bundling the bank 1 and bank 2 adjusters together saves significant labour on the second service.

P0019 su Mercedes E-Class

2005–2024

The M276 V6 in the W212 and W213 E-Class commonly sets P0019 due to camshaft adjuster magnet failure on bank 2. Mercedes parts are 250 to 400 EUR per side. The M278 V8 in higher trims has similar issues with more expensive bank 2 access. Always replace both bank adjusters together to avoid a return visit.

P0019 su Volkswagen Touareg

2005–2024

The Touareg 3.0 TDI V6 (CASA, CASB) is the prime P0019 candidate due to the well-documented timing chain stretch issue. VW issued multiple service campaigns. On the 3.0 TFSI EA837 V6, the bank 2 exhaust adjuster failure is identical to the Audi A6. Plan for 3000 EUR or more for full chain replacement at a VAG specialist.

Domande frequenti su P0019

Why does P0019 only appear on V-engines?

Bank 2 refers to the side of the engine that does not contain cylinder 1. Inline engines have only one bank, so P0018 and P0019 cannot appear on them. P0019 specifically requires a bank 2 exhaust camshaft sensor, which means the engine is at minimum a V6 or V8.

Is P0019 worse than P0017?

P0017 and P0019 are essentially the same fault on different banks. The mechanical severity is identical. However, P0019 is usually more expensive to repair because it implies a V-engine, where timing chain access requires more disassembly. On engines like the Audi 3.0 TFSI, the supercharger and intake manifold must come off.

Can I just replace the bank 2 VVT solenoid first?

Yes, it is the cheapest first step at 80 to 300 EUR for the solenoid plus 60 to 200 EUR labour. If the solenoid fixes the code, great. If P0019 returns within a few weeks, you are dealing with a stretched chain and the solenoid replacement was diagnostic data, not wasted money. Always change oil at the same time.

How long does a timing chain job take on a V6?

Plan for two to three full days at a workshop. On the Audi 3.0 TFSI, removing the supercharger, intake, and front engine accessories is half a day. The chain work itself is another half day. Setting the chains, reassembly, and test drive is another full day. Labour totals 15 to 25 hours depending on the engine.
