- The sensor is located on the transmission bellhousing at the rear of the engine; access is tight but DIY is possible.
- The most common trouble code is P0320.
- For best results, choose an OEM Mopar sensor or a top-tier aftermarket brand like NGK (NTK) or Delphi to avoid premature failure.
Symptoms of a Failing Crankshaft Position Sensor
When the crankshaft position sensor on a 1996-2000 Dodge Grand Caravan starts to fail, the signs are often hard to ignore. A classic symptom for these vans is the engine stalling unexpectedly once it has warmed up, then refusing to restart until it has cooled down. This can leave you stranded. Other common signs include:
- Engine Won't Start: The engine will turn over (crank) but won't fire up and run.
- Rough Idling: The engine may shake or vibrate when the van is stopped.
- Engine Misfires: You might feel a stumble or hesitation as you drive.
- Check Engine Light: A failing sensor will often trigger the Check Engine Light and store a diagnostic trouble code, most commonly P0320. 🎬 Watch: How to diagnose a P0320 circuit failure
- Sudden Stalling: The engine might cut out while you are driving, which can be very dangerous. 🎬 See a breakdown of 7 bad crank sensor symptoms
P0320 Trouble Code
The most common trouble code associated with a failing crankshaft position sensor is P0320 (Ignition/Distributor Engine Speed Input Circuit). This code means the engine's computer has detected an interruption or problem with the signal from the crankshaft sensor. While other issues can cause this code, a faulty sensor is the most frequent culprit.
Choosing the Right Aftermarket Sensor
For many electronic parts on these Dodge vans, not all aftermarket brands are created equal. Owner and mechanic experiences suggest that while some aftermarket sensors work well, others can be unreliable or fail quickly. It is often recommended to use an OEM Mopar part, but some high-quality aftermarket brands are known to be reliable alternatives.
Here is a general breakdown of brand quality based on community feedback:
- Top Tier (OEM Equivalents): Brands like NGK (NTK) and Delphi are often considered to be high-quality and reliable, sometimes even supplying the original parts to the manufacturer. Standard Motor Products (Standard Ignition) is also generally well-regarded.
- Mid Tier (Value): Brands like Dorman, Walker Products, and Holstein often provide a good balance of price and quality. They are a popular choice for DIY repairs, though some users report mixed results with sensitive electronics.
- Economy Tier: Lesser-known or store-brand sensors can be a gamble. While the low price is tempting, some have been reported to be dead-on-arrival or fail within a short period. If you choose an economy part, be prepared for the possibility of needing to replace it again sooner.
Pro Tip: Many experienced owners recommend sticking with Mopar or a top-tier aftermarket brand like NGK/NTK for critical sensors like the crankshaft position sensor to avoid repeat repairs and being stranded.

Frequently Asked Questions (FAQ)
Where is the crankshaft sensor located on a 1996-2000 Grand Caravan?
For the common 3.3L and 3.8L V6 engines, the crankshaft position sensor is located on the top of the transmission bellhousing, at the back of the engine. It can be difficult to see and reach, tucked under other components. 🎬 Watch: Finding the sensor location on a 3.8L engine Access is typically from underneath the vehicle.
Can I replace this sensor myself?
Yes, this is a DIY-feasible repair for someone with moderate mechanical skill. The main challenge is accessing the sensor's single 10mm bolt due to the tight space. You will likely need a ratchet with an extension. It is easier to reach from underneath the van.
Are there any recalls for this part?
There are no specific recalls found for the crankshaft position sensor itself on the 1996-2000 Dodge Grand Caravan. However, there have been recalls on other model years and vehicles for related components, like the tone wheel that the sensor reads, which can cause similar stalling symptoms. Always check for recalls specific to your vehicle's VIN on the NHTSA website.
What happens if I don't replace a bad crankshaft sensor?
Ignoring a failing crankshaft sensor will lead to worsening symptoms. The intermittent stalling will likely become more frequent, and eventually, the vehicle may not start at all. A sudden engine stall while driving is a significant safety hazard.
