Engine Crankshaft Position Sensor Guide for 1990-1995 Dodge Caravan
Solve common stalling, no-start, and rough engine performance on your second-generation Dodge Caravan.
- A failing crankshaft sensor is a common cause of stalling and no-start issues on these Caravans.
- Driving with a faulty sensor is unsafe because the engine can shut off at any time.
- Part quality is critical; cheap aftermarket sensors are known to fail quickly.
- For best results, choose a sensor from a reputable brand like NTK or Standard Motor Products.
Is Your Caravan Stalling or Refusing to Start?
A failing crankshaft position sensor is a common reason for engine problems in many vehicles, including the 1990-1995 Dodge Caravan. When this sensor starts to go bad, it sends incorrect signals—or no signal at all—to your engine's computer. This can cause your engine to suddenly shut off while driving, which is a serious safety concern. It can also prevent the engine from starting in the first place.
Warning: A Failing Sensor is a Safety Hazard
An engine that stalls unexpectedly, especially in traffic, can lead to a crash. If you suspect your crankshaft position sensor is failing, it is not recommended to drive the vehicle until it has been repaired.
Symptoms of a Bad Crankshaft Position Sensor
Look out for these common signs of failure. You might experience one or several of them, and they may be intermittent at first.
- Engine Stalls Unexpectedly: The engine may stall after it has warmed up and then refuse to restart until it has cooled down.
- Engine Cranks but Won't Start: You'll hear the starter trying, but the engine never fires up because the computer isn't getting the signal it needs for spark and fuel.
- Check Engine Light: A failing sensor will often trigger the check engine light. For these models, you may see an OBD-I code 11.
- Rough Idle and Engine Vibration: The engine may shake, sputter, or run unevenly when you're stopped.
- Engine Hesitation or Bucking: While driving, the van may jerk or hesitate as the sensor signal cuts in and out.
- Reduced Fuel Economy: With incorrect timing, the engine burns fuel less efficiently.
Choosing the Right Aftermarket Sensor
For a critical sensor like this, quality matters more than price. Forum discussions among Dodge and Chrysler owners consistently show that using a cheap, low-quality sensor often leads to it failing again in a short amount of time. It is worth spending a little more on a reputable brand to avoid doing the job twice.
| Brand Tier | Brands | General Assessment |
|---|---|---|
| Tier 1: Recommended | NTK, Standard Ignition (Standard Motor Products) | Often cited as the original equipment (OEM) manufacturer for Mopar parts. These brands have a strong reputation for reliability and are the preferred choice after Mopar. |
| Tier 2: Acceptable | Delphi | Delphi is a major OEM supplier for many car brands, but reviews for Chrysler applications are mixed. Some users have success, while others report early failures. A reasonable option if Tier 1 brands are not available. |
| Tier 3: Economy / Use with Caution | Dorman, Walker Products, Global Parts, Motorad, True Tech, Spectra | These brands offer a lower price point, but are generally considered lower quality for electronic sensors. There is a higher risk of premature failure or dead-on-arrival parts. Use these if budget is the primary concern, but be aware of the potential for future issues. |
Pro Tip: OEM vs. Aftermarket
While an original Mopar sensor is always a good choice, they can be expensive or discontinued for older vehicles. Brands like NTK are often the actual manufacturer for Mopar, so you can get the same quality part without the dealership price tag.
Frequently Asked Questions (FAQ)
Where is the crankshaft position sensor located on a 1990-1995 Dodge Caravan?
The sensor is typically located on the rear of the engine block where it meets the transmission, often on the bell housing. Depending on your engine (2.5L, 3.0L, 3.3L), you may need to access it from underneath the vehicle. It is held in place by a single 10mm bolt.
Can I replace this sensor myself?
Yes, this is a DIY-feasible job for someone with basic tools. The main challenge is often reaching the sensor due to its awkward location. You may need to remove the battery and battery tray for better access on some models. The part itself is only held by one bolt.
Are there any recalls for this part?
Searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any specific recalls or technical service bulletins (TSBs) for the crankshaft position sensor on the 1990-1995 Dodge Caravan model years.
Why did my van stall when it got hot but restart after cooling down?
This is a classic symptom of a failing electronic sensor. As the sensor's internal components heat up, they can fail and stop sending a signal, causing the engine to stall. After the sensor cools down, the connection can be temporarily restored, allowing the engine to start again until it heats up.
