The dreaded P0016 code. If you own a 2007 Mercedes E350, you might have encountered this frustrating issue. This comprehensive guide provides everything you need to know about the P0016 code on a 2007 Mercedes E350, including causes, diagnostics, and solutions, empowering you to tackle this problem effectively.
Understanding the P0016 Code
The P0016 code signifies a “Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A)”. In simpler terms, it means there’s a timing discrepancy between the crankshaft and camshaft on the engine’s bank 1. This misalignment can lead to a range of performance problems.
Common Causes of P0016 in a 2007 Mercedes E350
Several factors can trigger the P0016 code in your E350. Common culprits include:
- Stretched or worn timing chain: Over time, the timing chain can stretch, causing the synchronization between the crankshaft and camshaft to drift.
- Faulty camshaft position sensor: A malfunctioning sensor can send incorrect signals to the engine control unit (ECU), leading to the P0016 code.
- Worn crankshaft position sensor: Similar to the camshaft sensor, a faulty crankshaft sensor can disrupt the timing correlation.
- Low oil pressure or contaminated oil: Insufficient oil pressure or dirty oil can hinder the proper functioning of the variable valve timing system, contributing to the P0016 code.
- Wiring issues: Damaged or corroded wiring to the sensors can interrupt communication and trigger the code.

Diagnosing the P0016 Code
Accurately diagnosing the root cause of the P0016 code is essential for an effective fix. Here are some steps to take:
- Use an OBD-II scanner: Retrieve the specific P0016 code and any other related codes.
- Visually inspect the wiring and connectors: Check for any damage, corrosion, or loose connections.
- Check the oil level and condition: Ensure the oil level is correct and the oil is clean.
- Test the camshaft and crankshaft position sensors: Use a multimeter to check the sensors’ resistance and voltage output.
How to Fix the P0016 Code in a 2007 Mercedes E350
The fix for the P0016 code depends on the diagnosed cause. Here are some potential solutions:
- Timing chain replacement: If the timing chain is stretched or worn, it needs to be replaced. This is a complex repair that requires specialized tools and expertise.
- Camshaft/Crankshaft position sensor replacement: If a sensor is faulty, replacing it is a relatively straightforward procedure.
- Oil change and oil filter replacement: Fresh, clean oil can help resolve issues related to oil pressure and contamination.
- Wiring repair or replacement: Repairing or replacing damaged wiring can restore proper communication between the sensors and the ECU.
