Hey y’all, it’s your boy Matthew here and I’ve got a funny story for ya. So, I was working on my buddy’s 5.7 Hemi the other day and he asked me to check the oil pressure sensor.
I’m thinking to myself, “no problem, I got this.” I pop the hood, look around, and I swear to God, I couldn’t find the darn thing anywhere.
I mean, I looked everywhere. I even went as far as to consult the owner’s manual and still, nothing. I must’ve looked like a complete moron, standing there with a dumbfounded look on my face.
My buddy comes over and says, “Dude, it’s right there.” And I’m like, “Where?” And he points to this tiny little thing hidden behind the exhaust manifold.
I couldn’t stop laughing at myself. But, it’s all good, because now I know where the oil pressure sensor is on a 5.7 Hemi and I’m here to share that knowledge with you.
The oil pressure sensor on a 5.7 Hemi is located behind the exhaust manifold.

What The Heck Does The Oil Pressure Sensor Do?
The oil pressure sensor is responsible for monitoring the oil pressure in your engine. It sends a signal to the engine control module (ECM) which then displays the oil pressure on the dashboard.
If the oil pressure is too low, the sensor will send a signal to the ECM to turn on the low oil pressure warning light. It’s basically like the canary in the coal mine for your engine’s oil system.
Why The Heck Should I Care About The Oil Pressure Sensor?
Well, if the oil pressure sensor is not working properly, you may not know when your oil pressure is too low.
This can lead to serious damage to your engine and can result in costly repairs. It’s important to regularly check and maintain the oil pressure sensor to ensure your engine is running smoothly.
How The Heck Do I Check The Oil Pressure Sensor?
It’s simple, all you need is a digital multimeter. First, locate the oil pressure sensor behind the exhaust manifold.
Then, disconnect the sensor’s electrical connector. Next, set your multimeter to the lowest ohms setting and touch the multimeter’s probes to the sensor’s terminals.
The reading should be between 4-10 ohms. If the reading is outside of this range, the sensor may be faulty and should be replaced.
Fun Fact:
Did you know that the 5.7 Hemi engine was first produced in 2003 by Chrysler and it’s still in production today? It’s known for its high performance and durability.
My Personal Experience
I’ve personally worked on a lot of 5.7 Hemi engines and I can tell you, they’re a blast to work on. They have a ton of power and they’re built to last.
One time, I remember working on a 5.7 Hemi that had over 200,000 miles on it and it was still running like a top.
I was honestly impressed by the engine’s longevity. I think it’s a testament to the engineering that went into designing these engines.
Frequently Asked Questions
Q: How often should I check the oil pressure sensor?
A: It’s recommended to check the oil pressure sensor every time you change your oil.
However, if you notice any warning lights or abnormal behavior with your engine, it’s best to check the sensor immediately.
Q: Can I replace the oil pressure sensor myself?
A: Yes, you can replace the oil pressure sensor yourself with the proper tools and knowledge. However, if you’re not comfortable working on your engine, it’s best to take it to a professional.
Q: Can low oil pressure cause damage to my engine?
A: Yes, low oil pressure can cause serious damage to your engine. It’s important to regularly check and maintain your oil pressure sensor to ensure your engine is running smoothly.
In Conclusion
So there you have it folks, the oil pressure sensor on a 5.7 Hemi is located behind the exhaust manifold. It’s an important part of your engine’s oil system and should be checked and maintained regularly.
And remember, if you ever find yourself scratching your head trying to locate the sensor, just remember, it’s probably hiding behind the exhaust manifold. Happy wrenching!
