Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace a MAP sensor on this 2003 Chevy Monte Carlo with the 3.4 liter V6 Engine. The items you'll need for this include a new MAP Sensor from 1AAuto.com, a 7mm socket, and a ratchet.
Your MAP sensor's located right here, and it's got two bolts that go all the way through. Just push this harness through and then remove the bolts from the other side of the MAP sensor. We'll fast forward as Mike does this. Now push down on the tab of the harness and pull it free. Then lift up on the MAP sensor. Pulls from that hose. On the right is the old MAP sensor, on the left is the new one from 1A Auto. You can see they're identical and they'll fit exactly the same. Push the harness back into your MAP sensor. And you don't want to push it down all the way just yet. Just do it about half the way onto the harness. Then push it down onto that vacuum hose. Once you've got the hose all the way on, push the harness on the rest of the way. Then line it up and replace those two bolts. Clip this harness back into the bracket and you're all set.
We hope this video helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393. We're the company that's here for you on the Internet and in person.

My old 94 Chevy truck runs much better once more with this new MAP sensor. Don't forget to replace the vacuum line with new hose when you replace this part.
inexpensive, but did the job

wasn't the $60-70 "replacement" part, but did the job. fixed the hard transmission shift and turned off the Check Engine Light. now if it had fixed my ABS warning light i would give it 5 stars!
Didn't fit!

Connector did not mate properly. Engine would not start with this sensor installed. Purchased a sensor from local parts house which worked great!
Lasted two miles.... Maybe....

I bought a 1994 Wrangler about a month ago. I decided to replace all the sensors because I didn't know their age, not because they were bad. The throttle position sensor didn't make it from my driveway to the gas station before it failed. I limped the Jeep home and put my old TPS back in and disconnected the battery to clear the check engine light. Jeep ran perfectly after that. I'm looking for my receipt so I can send it back......
On time correct part the 1st time!

I went to auto stores to get some quotes on this part. I was going to go with the cheapest one until my wife said to look online. I am so glad I did. You had the cheapest. I almost paid twice as much at a store. Ill be checking yalls price before any auto store.

My new MAP sensor works perfectly just like the window regulators, rotors, pads and new hubs. All parts that I have purchased from 1A auto have fit perfectly and performed like OEM parts that I replaced.

Easy install. Noticed an immediate improvement in the idle of the engine. The exhaust doesn't have that raw fuel odor anymore. Hoping for better fuel mileage also.
