Chrysler Pacifica 2017-2024 Engine Crankshaft Position Sensor Replacement Guide
Experiencing stalling, a no-start issue, or a check engine light in your Pacifica? Your crankshaft sensor could be the problem.
- A stalling engine is the most dangerous symptom; do not drive if you suspect the sensor is failing.
- The most common trouble code is P0335, which confirms a crankshaft sensor issue.
- For this critical sensor, it is highly recommended to use an OEM (Mopar) or a premium aftermarket brand like NTK, Delphi, or Standard Ignition for reliability.
- The sensor is located on the rear of the engine block and is accessed from underneath the vehicle.
Is Your Pacifica's Crankshaft Position Sensor Failing?
A bad crankshaft position sensor can cause problems that range from annoying to dangerous. Because this sensor is essential for engine operation, a failure can leave you stranded. Recognizing the symptoms early is key to avoiding a breakdown.
Key Failure Symptoms:
- Check Engine Light: This is often the first sign. A scan tool will typically show the diagnostic trouble code P0335.
- Engine Stalling: The engine may shut off unexpectedly while you are driving, especially as it warms up or when you come to a stop. This is a major safety hazard.
- No-Start or Hard Starting: Your Pacifica may crank over but refuse to start. Or, it may take much longer than usual to fire up.
- Rough Idle and Misfires: The engine may vibrate, shake, or sound like it's stumbling when you are stopped.
- Hesitation During Acceleration: You might notice a lack of power or a sluggish response when you press the gas pedal. 🎬 Watch: How to identify and fix common sensor failure symptoms
Choosing the Right Aftermarket Crankshaft Sensor
When replacing a critical sensor like this, quality matters. While budget parts are available, a faulty replacement can fail quickly, leaving you with the same problem. Here’s how the available brands generally stack up for your Pacifica.
Tier 1: OEM and Premium Aftermarket
These brands are known for reliability and are built to meet or exceed original factory specifications. For a part that can leave you stranded, spending a little more here is a wise investment.
- Mopar (OEM): The original factory part. It's the benchmark for fit, function, and longevity.
- Delphi, NGK (NTK), and Standard Ignition (SMP): These are top-tier aftermarket manufacturers. Delphi is a major OE supplier, and NTK (the sensor brand for NGK) is highly recommended in forums for Chrysler vehicles. Standard is a long-trusted name in engine management parts.
Tier 2: Standard Aftermarket Brands
These brands offer a balance of value and quality. They are a good option for budget-conscious repairs, but may not have the same level of validation as premium brands.
- Dorman and Walker Products: These brands provide a cost-effective alternative. While functional, for a critical sensor like the crankshaft position sensor, most mechanics would recommend choosing from Tier 1.

Frequently Asked Questions
Where is the crankshaft position sensor located on a 2017-2024 Chrysler Pacifica?
The crankshaft position sensor on the 3.6L engine is located on the rear of the engine block, near the transmission bell housing. You will 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 moderate mechanical skill. While the sensor is only held by one bolt, access is tight. You will need to safely raise the vehicle with a jack and jack stands to work from below. The difficulty is not in the task itself, but in reaching the sensor's location.
🎬 Watch: Step-by-step crankshaft sensor replacement for 2011-2025 PacificasIs a bad crankshaft sensor related to the 2017 Pacifica stalling recall?
Partially. A recall was issued for some 2017 Pacifica models for engine stalling, but the official cause was a software issue requiring an update to the engine control module. However, the symptoms of that issue are identical to a failing crankshaft position sensor. If your van has had the recall service performed but is still stalling, the sensor is a primary suspect, especially if you have a P0335 code.
What's the difference between a crankshaft and a camshaft position sensor?
They work together but measure different things. The crankshaft sensor tracks the position of the crankshaft at the bottom of the engine. The camshaft sensors (the Pacifica has four) track the position of the camshafts in the cylinder heads. Both are critical for engine timing, but they will produce different trouble codes when they fail.
