1997-2001 Plymouth Prowler Crankshaft Position Sensor: A Complete Guide
Solving stalling, no-start, and rough running issues in your Plymouth Prowler starts with this critical sensor.
- A failing crank sensor is a primary cause of stalling and no-start issues in a Prowler.
- Due to the risk of stalling while driving, this part should be replaced as soon as symptoms appear.
- For reliability, choose an OEM (Mopar) or a top-tier aftermarket brand like NTK, Standard Ignition, or Walker Products.
- Replacement is possible for a DIYer, but access to the sensor on the transmission housing is tight.
Is Your Prowler Stalling or Refusing to Start?
A failing crankshaft position sensor is a common reason for engine problems in many vehicles, including the Plymouth Prowler. Because this sensor is essential for engine timing, when it starts to go bad, it can cause symptoms that range from annoying to dangerous. The most serious issue is the engine stalling while you are driving, which can happen without warning. You might also find the engine cranks but won't start, or it takes a very long time to fire up. Other signs include a rough idle, engine misfires, poor acceleration, and a decrease in fuel economy. Often, a failing sensor will trigger the Check Engine Light on your dashboard.
Critical Part Warning
A complete failure of the crankshaft position sensor will prevent the engine from starting. An intermittent failure can cause the engine to shut off while driving, creating a significant safety hazard. Do not ignore the symptoms of a failing sensor.
Choosing the Right Aftermarket Sensor for Your Prowler
When it comes to critical electronic sensors like the crankshaft position sensor, not all aftermarket parts are created equal. For many Chrysler vehicles, there is a strong consensus among mechanics and owners that using a high-quality part is essential to avoid future problems. Low-quality sensors are known to fail quickly or be dead-on-arrival right out of the box.
Brand Quality Tiers
- Tier 1 - OEM or OEM-Equivalent: The safest choice is always an original Mopar part from a dealer or a sensor from the original equipment manufacturer, such as NTK. These parts are built to the exact specifications for your Prowler and offer the best reliability, though they cost more.
- Tier 2 - Reputable Aftermarket: Brands like Standard Ignition (SMP) and Walker Products have a long history in the aftermarket. They are generally considered a good balance of price and quality. While they may not be identical to the OEM part, they are a reliable choice for most repairs.
- Tier 3 - Budget-Friendly Options: Brands like Dorman, Prenco, and True Tech fall into this category. Dorman's quality can be inconsistent; some parts are excellent, while others are known to fail. These brands can get your vehicle running on a tight budget, but the risk of premature failure is higher.
Pro Tip: Given the safety-critical nature of this part (preventing engine stalling), investing in a Tier 1 or Tier 2 brand is highly recommended for long-term peace of mind. A few extra dollars now can save you from being stranded later.
Known Issues, Recalls, and Service Bulletins
As of early 2026, there are no specific NHTSA recalls or Technical Service Bulletins (TSBs) for the engine crankshaft position sensor on the 1997-2001 Plymouth Prowler. While other Chrysler vehicles have had recalls related to the tone wheel that the sensor reads, the Prowler was not included. Any issues you experience are likely due to normal part wear and aging rather than a specific manufacturing defect.

Frequently Asked Questions
Can I replace the crankshaft sensor myself?
Yes, this is a feasible DIY job for someone with basic mechanical skills. The sensor is located on the passenger side of the transmission bell housing. Access is tight, and you will need to work from underneath the vehicle. 🎬 Watch: A mechanic's guide to replacing the sensor The sensor is held in by a single 10mm bolt. 🎬 See this walkthrough for installing the sensor Gently twisting the old sensor while pulling can help remove it without breaking it.
What is the most common error code for a bad crank sensor?
The most common Diagnostic Trouble Code (DTC) is P0320, which stands for "Ignition/Distributor Engine Speed Input Circuit Malfunction." 🎬 Watch: How to diagnose a P0320 circuit failure This code indicates that the ECM has lost the signal from the crankshaft position sensor. You may also see misfire codes for various cylinders.
Is an expensive sensor really better than a cheap one?
For this specific part, yes. The sensor's job requires precision. Cheaper sensors may use lower-quality magnets or electronics that can't withstand engine heat and vibration, leading to a weak or erratic signal and premature failure. Many professional mechanics will only install OEM or top-tier aftermarket sensors to avoid the job coming back to the shop.
What's the difference between a crank sensor and a cam sensor?
They work together. The crankshaft sensor tells the ECM the rotational speed and position of the bottom end of the engine. The camshaft position sensor does the same for the top end of the engine (valves). The ECM uses both signals to get a complete picture for precise fuel and spark timing.
