Ls1 map sensor location.
Get it as soon as wed oct 7.
This video is just me taking off the wiring and taking note of the sensors around the ls1 engine.
This map sensor is mounted directly to the intake manifold but others might be connected by a hose.
The ecm uses map sensor data to run crucial calculations such as engine load fuel injector pulse and spark advance.
With the ls3 engine general motors introduced a bosch map sensor in the same location as the ls2 manifold but with an attaching bolt.
Ive bought 2 different mass air flow sensors replaced all my 02 sensors n now its still giving me map sensor but now also all my 02 sensors again lol so thinking about taking it to the dealer now.
The map sensor is usually located in a few key places around the upper engine bay area.
Under or near the throttle body.
When at rest the map sensor reads atmospheric pressure at sea level 29 93 in.
3 bar map sensor manifold absolute pressure map sensor ls1 ls2 ls3 ls6 ls7 ls9 trans am firebird turbo camaro corvette.
I want to record and make the most detailed set of videos f.

Only 6 left in stock order soon.
Map sensor sorry took so long but it does sound the same n i back fire all the time now still cannot locate that sensor.
While electronically compatible with the ls1 ls6 ls2 map sensor the ls3 map sensor is not a direct fit to the early intake manifolds uses a different harness connector and its pin configuration is unique.
