Chrysler E Class Engine Oil Pressure Switch Guide (1983-1984)
Don't let a flickering oil light lead to engine failure in your 1983-1984 Chrysler E Class.
- Never drive with the oil pressure light on; you risk catastrophic engine failure.
- A flickering light at idle is the most common symptom of a failing switch, but always verify the oil level first.
- Replacement is an easy and inexpensive DIY job that can prevent major engine problems.
- For maximum reliability, choose a reputable aftermarket brand like Standard Ignition (SMP).
Is Your Chrysler E Class Oil Pressure Switch Failing?
The engine oil pressure switch is a small part that plays a huge role in protecting your 2.2L or 2.6L engine. Given the age of the 1983-1984 Chrysler E Class, this switch is a common failure point. When it fails, it can either provide a false warning or, worse, fail to warn you of a real oil pressure problem. Ignoring the signs can lead to the most expensive repair of all: a new engine.
Top 3 Symptoms of a Bad Oil Pressure Switch
- Flickering Oil Light: The most common symptom is the oil pressure light flickering, especially at idle, during stops, or when the engine is warm. As the switch wears out, it can give false readings when oil pressure is naturally lower at idle.
- Oil Light Stays On: If the switch fails electrically, it may cause the oil light to stay on constantly, even if the pressure is fine. While this could indicate a bad switch, it should always be treated as a serious low-pressure situation until verified.
- Visible Oil Leak: The switch itself can develop leaks over time. You may notice oil residue on the sensor or drips on the ground below its location on the engine block. This is a clear sign the switch needs immediate replacement.
Warning: Never Ignore the Oil Light
An illuminated oil pressure light means you should stop the engine immediately. Continuing to drive, even for a short distance, can cause severe, irreversible engine damage. Always verify the engine oil level first. If the level is correct, the problem could be the switch or a more serious internal engine issue. Do not drive the vehicle until the cause is identified.
Choosing the Right Aftermarket Oil Pressure Switch
For a vintage vehicle like the E Class, new OEM parts from Mopar are generally unavailable. The aftermarket is your primary source. Quality varies significantly, so understanding the brands is key.
Brand Tiers for Your E Class
- Professional Grade (Standard Ignition): Standard Motor Products (SMP) is a long-established American manufacturer known for producing high-quality engine management parts that meet or exceed OE specifications. They use durable materials like high-temperature polyimide film diaphragms to resist leaks and ensure longevity. For a critical part like this, choosing a trusted brand like Standard is a wise investment in reliability.
- Mid-Grade (Rostra Powertrain): Rostra is a certified manufacturer specializing in automotive electronics, including sensors and switches. While widely known for transmission components, their general product quality is considered reliable. This makes them a solid choice if a premium brand is not available.
- Economy (Global Parts): Brands in the economy tier are focused on providing a low-cost solution. While functional, there is limited public information available to verify the long-term quality or durability of sensors from brands like Global Parts. These parts may be a suitable budget fix, but may not offer the same lifespan or robust construction as higher-tiered brands.

Cost estimates are for reference only and may vary based on location, part availability, and your vehicle's specific engine (2.2L or 2.6L).
Pro Tip: Check the Connector
When replacing the switch, inspect the wiring connector. Oil leaking through a failed switch can contaminate the connector, causing a poor connection. Clean any oil out of the connector with electrical contact cleaner. If the connector or wiring is brittle or damaged, it should be repaired or replaced to ensure the new switch functions correctly.
Frequently Asked Questions (FAQ)
Is it safe to drive with a flickering oil light?
No. A flickering oil light indicates that your oil pressure is dropping to a dangerously low level, or the sensor is failing. You should not drive the vehicle, as you cannot be sure if it is a real pressure drop that could destroy the engine. Pull over safely, check the oil level, and have the vehicle inspected.
Where is the oil pressure switch located on a Chrysler E Class?
The location varies slightly between the 2.2L and 2.6L engines. Generally, you will find the oil pressure switch threaded into the engine block, often near the oil filter. It is a small, can-shaped sensor with a single electrical connector. Consulting a service manual for your specific engine is recommended.
Can I replace the oil pressure switch myself?
Yes, this is a very feasible DIY job for most home mechanics. It typically requires a deep socket or a special oil pressure switch socket. The process involves disconnecting the electrical connector, unscrewing the old switch, and installing the new one. A small amount of oil will drip out, so have a rag ready. The entire job usually takes less than 30 minutes.
Are there any recalls for the oil pressure switch on the 1983-1984 E Class?
There are no specific recalls or Technical Service Bulletins (TSBs) from the NHTSA related to the engine oil pressure switch for this vehicle. Any issues are typically due to the age and normal wear of the component.
