3 BAR MAP SENSOR for G*M DELPHI ACCEL DFI CHROME MSD TURBO

Cheap three bar map sensor I used on my Holley EFI. I compared it to another GM sensor and it was reading the same as an OE sensor. Great value for the money.

Not a 3 bar map sensor.

Worked great for my 5.7, 1989 silverado. Helped idle tremendously.

I got this as a gift for my husband. He said it's exactly what he needed so thumbs up!

When I first received this MAP sensor I wired it into my standalone ECU and then calibrated it. With key on sensor reads MAP KPA (315) at 5V. It should NOT do this. It should read 100KPA and no more than 1.5-1.75V. Despite this I thought maybe this particular sensor won't read unless it's getting vacuum/boost put to it. So I started up the vehicle and it was reading 120-180kpa (3-12psi of boost) when I was at 60kpa (18hg) in vacuum! It severely flooded my engine. I returned the product for a replacement and the 2nd one does the exact same thing! Terrible sensors. They also come in smelling like vic's vapor rub out the package, what's up with that?

As someone else indicated, this sensor reads almost 5 volts at atmospheric pressure. That’s because it’s a 1 bar sensor. This is not a 3 bar map sensor. Also, the included pigtail is the wrong plug for the included sensor. Pigtail IS for a 3 bar sensor, not the 1 bar being sold.

Used with mad 6al2 programmable. Map sensor worked great for 2 days, 3rd day the car started running horrible. Checked logs and noticed map sensor is constantly reading max pressure.
