Crankshaft Position Sensor for the 2003-2007 Nissan Murano: A Complete Guide
If your Murano is stalling or won't start, the crankshaft position sensor is a likely culprit.
- A failing sensor can cause your Murano to stall unexpectedly, which is a major safety hazard.
- A recall was issued for 2003 models for this exact issue, highlighting it as a known problem.
- Using a cheap, unbranded aftermarket sensor is risky; an OEM or OE-equivalent (like Hitachi) part is strongly recommended for this specific repair.
- Replacement is simple for a DIYer, requiring access from under the car and only one 10mm bolt to remove.
Understanding the Crankshaft Position Sensor in Your Murano
The 3.5L V6 engine in the first-generation Nissan Murano is known for being reliable, but its electronic sensors can be a weak point as the vehicle ages. The crankshaft position sensor is one of the most critical. It tells the engine's computer how fast the crankshaft is spinning and its exact position. Without this signal, your engine can't time fuel injection and spark correctly, leading to serious running issues. It's important not to confuse this part with the two camshaft position sensors, which are also common failure points but are located on the top of the engine.
Safety Alert: Recall and Stalling Risk
Nissan issued a recall for some 2003 Murano models due to a faulty crankshaft position sensor that could cause the engine to stall without warning (NHTSA Campaign ID: 03V455000). Even if your vehicle wasn't part of the recall, a failing sensor presents the same dangerous risk of the engine shutting off while driving. For this reason, addressing symptoms immediately is critical.
Choosing the Right Aftermarket Sensor: A Word of Caution
When it comes to electronic sensors on the Murano's VQ35DE engine, not all parts are created equal. Many owners and mechanics report that cheap, unbranded aftermarket crankshaft sensors are prone to premature failure, sometimes within weeks or months. This can leave you stranded again and require you to do the job twice. The original equipment (OE) manufacturer for Nissan is often Hitachi. If you choose an aftermarket part, selecting a reputable brand known for producing OE-quality components, like Hitachi, is strongly recommended for reliability. The original sensor was made of black plastic, but Nissan later updated the part to a more durable metal design to better handle engine heat. If your replacement part looks different from the original, it is likely the improved version.
Installation and Location
Replacing the crankshaft position sensor is a job most DIY mechanics can handle. The sensor is located on the front of the engine, near the bottom, where the engine block meets the transmission. You will need to access it from underneath the vehicle. It is held in place by a single 10mm bolt and has one electrical connector. After safely raising the vehicle, you simply disconnect the connector, remove the bolt, and swap the sensor. It's a good idea to apply a little fresh motor oil to the new sensor's O-ring before installation.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Part | $80 - $170 |
| New Aftermarket Part | $31.86 - $80 |
| Shop Labor | $82 - $140 |
| Total Professional Replacement | $187 - $289 |
Pro Tip: Check the Connector
Oil leaks from above can sometimes damage the sensor's electrical connector. When you replace the sensor, inspect the connector and wiring for any signs of oil contamination, brittleness, or damage. A bad connection can mimic the symptoms of a failed sensor.
Frequently Asked Questions (FAQ)
What is the main trouble code for a bad crankshaft sensor?
The most common OBD-II trouble code is P0335, which stands for "Crankshaft Position Sensor 'A' Circuit Malfunction". If your check engine light is on, getting the codes scanned is the first step.
Can I drive my Murano with a bad crankshaft sensor?
No, it is not recommended. The engine can stall at any time, including on the highway at high speeds, which is a serious safety risk. If you suspect the sensor is failing, you should stop driving the vehicle until it is repaired.
Where is the crankshaft sensor located?
It is located on the front of the engine near the oil pan, where the engine meets the transmission. It is accessible from underneath the car and is held in by a single 10mm bolt.
Is this a difficult repair to do myself?
For most people with basic tools, this is a straightforward DIY repair that can be done in under an hour. You will need to safely lift and support the front of the vehicle to gain access from below.
