Dodge 600 Engine Oil Pressure Switch Guide (1983-1988)
Is your oil light acting up? Here’s what Dodge 600 owners need to know about a failing oil pressure switch.
- A flickering or constantly lit oil light on a Dodge 600 is most often a bad pressure switch, not a major engine problem, assuming oil level is correct.
- This is a very easy and inexpensive DIY repair; you can replace the switch in under 30 minutes with basic tools.
- Quality aftermarket brands like Standard Ignition are a reliable choice; OEM parts are likely unavailable.
- Never ignore an oil light accompanied by engine knocking or ticking—stop the car immediately to prevent engine destruction.
Is Your Dodge 600 Oil Light On?
A faulty engine oil pressure switch is a common issue on older vehicles like the 1983-1988 Dodge 600. The symptoms are often alarming, but the fix is usually simple and inexpensive. The biggest mistake you can make is ignoring the warning light, as you won't know if it's a bad sensor or a real oil pressure problem that could destroy your engine.
Common Failure Symptoms
- Oil Light Stays On: If the oil level is full but the warning light stays on, the switch is the most likely culprit.
- Flickering Oil Light: The light may flicker, especially at idle, during sharp turns, or when braking. This can happen if the sensor is failing or if the engine oil level is low. Always check the oil first.
- Oil Leaks: The switch itself can fail and leak oil. You may see oil on the sensor, its electrical connector, or dripping from the engine block in that area.
- Warning Light Never Comes On: The switch can also fail in the 'off' position. You should see the oil light briefly illuminate when you turn the key to the 'on' position before starting the engine. If it doesn't, the bulb or the switch could be bad.
Warning: Real Low Oil Pressure
If the oil light is on and you hear new ticking, knocking, or grinding noises from the engine, stop the vehicle immediately. This indicates a true lack of oil pressure, and continuing to drive will cause catastrophic engine failure.
Choosing the Right Aftermarket Switch
For a vehicle from this era, new original equipment (OEM) Mopar parts are generally not available. Aftermarket brands are your only realistic option. The good news is that this is a simple part, and several reputable aftermarket companies produce reliable replacements.

Pro Tip: Get the Right Socket
These switches often require a special deep socket to remove and install them without damaging the plastic connector part. While a standard deep socket may work, an oil pressure switch socket is inexpensive and makes the job much easier. Also, ensure the new switch has thread sealant on the threads or apply a small amount of Teflon tape to prevent leaks.
Frequently Asked Questions (FAQ)
Where is the oil pressure switch on my Dodge 600?
On Dodge 600 models with the 2.2L or 2.5L engine, the oil pressure switch is typically screwed into the engine block. Look on the back of the engine, near the distributor and oil filter housing. It is a small, bell-shaped sensor with a single electrical wire attached to the top.
Can I drive with a bad oil pressure switch?
If you have confirmed the engine oil level is correct and the engine is not making unusual noises, you can likely drive the vehicle. However, you have lost your primary warning system for low oil pressure. It is a critical safety feature, and the part is inexpensive and easy to replace, so it should be fixed as soon as possible.
Are there any recalls for the Dodge 600 oil pressure switch?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls or technical service bulletins (TSBs) related to the engine oil pressure switch for the 1983-1988 Dodge 600. Failures are simply due to the age of the component.
Is this a difficult or expensive repair?
No, this is one of the easiest and cheapest repairs you can perform. The part itself costs between $9 and $27. A mechanic should only charge for a minimal amount of labor, likely less than half an hour. Most DIY mechanics can replace this part in under 20 minutes with basic tools.
