Having trouble starting your Murano or experiencing sudden stalling? Your crankshaft position sensor might be the culprit.
- A failing crankshaft sensor is a known issue, with symptoms like stalling and no-start. A recall was issued for 2003 models for this problem.
- The most common fault code is P0335.
- For aftermarket parts, stick to reputable brands like Hitachi, Delphi, or NGK, as cheap sensors are known to fail prematurely.
- Replacement is a simple DIY job for most, located at the bottom front of the engine and held by one 10mm bolt.
Symptoms of a Failing Crankshaft Position Sensor
A bad crankshaft position sensor can cause several noticeable problems with your Nissan Murano. One of the first signs is often the Check Engine Light illuminating on your dashboard. You might also experience difficulty starting the engine, where it cranks for a long time before finally turning over, or it may not start at all. Sudden stalling while driving, especially when the engine is hot, is another serious symptom. Other signs include a rough idle, engine vibrations, misfires, and a noticeable decrease in fuel economy.
Recall and Known Issues
Nissan issued a recall (NHTSA Campaign ID: 03V455000) for some 2003 Murano models due to improper solder joints on the circuit board for the crankshaft position sensor. This defect could cause the engine to stall without warning. While the official recall period may be over, it highlights a known vulnerability with the original sensors. Additionally, many owners have found that the original plastic sensors are prone to failure from heat, and updated OEM parts often feature a metal housing for better durability.
Choosing the Right Aftermarket Sensor
When replacing the crankshaft position sensor on your Murano, you have a choice between OEM (Original Equipment Manufacturer) and aftermarket parts. While OEM is often recommended, several aftermarket brands offer a reliable and more affordable alternative. For this specific part on Nissan vehicles, quality can vary significantly between brands.
- Premium Aftermarket (Recommended): Brands like Hitachi, Delphi, and NGK (NTK) are often considered top-tier choices. Hitachi was an original equipment supplier for Nissan, so their parts are expected to meet high standards. Many owners report success with these brands, finding them to be a reliable alternative to the more expensive dealer part.
- Reputable Standard Aftermarket: Brands like Standard Motor Products (SMP) and Beck Arnley generally have a good reputation. They often provide a good balance of quality and value. However, some forum users have had mixed results, emphasizing the importance of buying from a reputable source.
- Economy Brands: While brands like Dorman and other lower-priced options are available, they can be a gamble for critical sensors like the crankshaft position sensor. Some owners report these parts failing quickly, leading to the same problems. For a part that can leave you stranded, investing in a higher-quality sensor is often worth the extra cost.
Pro Tip: Many Nissan technicians and experienced owners recommend replacing both the crankshaft and camshaft position sensors at the same time, as they are similar in design and tend to fail around the same mileage. This can save you from a future breakdown and another repair job.
