Replace your factory MAP sensors that blow out when you turn up your boost with these GM 3 bar map sensors in just a few minutes!

PCM file update required, See "Option 2" on our ZZP LNF 1.0 PCM page.

LNF only!

Includes:

  • (2) GM 3.3 bar map sensors (good to 33psi)
  • (2) O-rings
  • (2) GM Plug and Play wire harnesses

ECU Programming

In HP Tuners, set the MAP sensor linear to 65.89kPa, MAP sensor offset to -6.35kPa, Boost sensor linear to 65.89kPa, and Boost sensor offset to -6.35kPa.

These are an intended upgrade for the 2.0 turbo Cobalt SS, HHR SS, Sky Redline, and Solstice GXP. The 2.0 LHU Regal does not need these as they come stock with 4 bar MAP sensors.

GM Stage 1 Sensors

I’ve been looking high and low for these sensors. They were the exact same types used in my 09 Chevy HHR SS I just acquired. Totally glad I purchased them and with its overall performance. Thank you to ZZperformance for having them available

Easy and fast to install

Had one pin push in on the wiring connector - pushed it back into place, reconnected and I was good to go. Took about 10 minutes to install.

Needed sensors

At 25 psi, the stock sensors were throwing codes. Replacing them with these stage 1 sensors didn’t help at first. The ECU was tuned for stock sensors. Once the ECU was reprogrammed, for these sensors, the car started running great with no CEL

GM S1 Working, Not too Difficult to Install

This was a fairly straightforward install on my '09 SS Turbo with some slight changes. The harnesses are too long but they make the right connections. A long screwdriver is needed for the bottom end and some modification to the part to make it fit well there. There is only one spot for screw on the topside vs. 2 in the stock modult as these don't match perfectly either but it will wiggle in and do the job. Here's a link to a video I used to help with the install: https://www.youtube.com/watch?v=qQXsnVvEZPw&t=7s&ab_channel=JosephDiFeo
