P0018 : Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor A)

P0018 means the crankshaft and the intake camshaft on bank 2 are not in the correct rotational relationship. Bank 2 contains the cylinder not housing cylinder 1, so this code only appears on V-engines and some inline engines with multiple banks. The ECU detects the bank 2 intake cam position deviates from the commanded angle, typically due to a stretched chain, failed VVT solenoid, or low oil pressure.

P0018 est un code defaut lie a allumage, classe en gravite high. Lorsque le calculateur de ton vehicule detecte cette condition, il enregistre P0018 et allume le voyant moteur.

Si ton vehicule a declenche P0018, tu peux remarquer un ou plusieurs de ces symptomes :

• Check engine light illuminated
• Rattle from the front of the engine on cold start (especially on V6/V8)
• Rough idle and possible misfire on bank 2 cylinders
• Hard starting, particularly when the engine is warm
• Reduced power and hesitation under acceleration
• Increased fuel consumption

Voici les causes les plus courantes de P0018, classees selon la probabilite qu'elles soient en cause :

Non, regle ca immediatement. Drive only short distances to reach a workshop. P0018 is a bank 2 (typically intake cam) correlation fault, meaning your engine is a V6, V8, V10, or V12. Continued driving with a stretched timing chain risks bending valves on interference designs.

Suis ces etapes pour identifier la cause profonde de P0018 :

1. Check engine oil level and condition. V-engines are particularly sensitive to oil quality and pressure because both banks share the oil pump. Top up or change with the manufacturer-specified viscosity and clear the code
2. Listen for cold-start rattle from the front of the engine. On V6 and V8 engines a stretched chain or worn tensioner makes a distinct 1 to 5 second rattle until oil pressure builds
3. Use a scan tool to monitor live cam phasing data on bank 2. Compare actual versus commanded intake cam angle. Deviations over 5 to 10 degrees confirm mechanical timing fault
4. Test the bank 2 intake VVT solenoid. Resistance typically 6 to 13 ohms. Inspect the screen for debris. A clogged screen blocks oil to the phaser and triggers P0018
5. If the solenoid is good and oil pressure is normal, suspect the timing chain or guide wear on bank 2. A workshop will need to remove the valve cover for inspection. On many V-engines this is bank 2 specifically, not both banks
