Good question, santoscourtney! Look for frayed wires or loose connections. Inspect the harness that connects the sensor, as that can wear over time.

22

Don’t forget about the ECU! If both the sensor and wiring are fine, a malfunctioning engine control unit could also be the culprit. It’s rare, but it happens.

Thanks for mentioning the ECU, yrussell. It certainly complicates things, doesn’t it? How can we test the ECU properly?

24

Running a diagnostic with a professional scanner can help detect if the ECU is working correctly. But be prepared for potential costs! It can get pricey.

All this talk makes me feel like a mechanic! I might just challenge the local shop to a wrench-off! Just kidding, but seriously, it seems overwhelming.

Stay positive, brandygreen! Many have resolved the issue without breaking the bank. Looking carefully at the sensor and wiring usually helps narrow it down.

I find it interesting how many things can go wrong. I’ve heard if you reset the code after repairs, sometimes the issue resolves itself if it’s been intermittent. Anyone else tried that?

Yeah, I’ve done that before! It’s worth a shot, especially if you’re just dealing with a temporary glitch.

Reminds me of my last experience with codes! I had to reset it about five times before it finally went away. Sometimes patience is key!

I had the P2227 code pop up on my '15 Cruze too! Turns out, it was just a loose connector on the MAP sensor. Tightened it up, and the code cleared. Easy fix!

That’s great to hear! I have a '16 model, and I’m worried it might be something similar. Did you erase the code yourself afterward?

32

Yes, I used an OBD-II scanner to clear it. If you can, definitely get a scanner—super helpful for DIY repairs!

33

I got P2227 after getting my car tuned. It turned out to be a bad MAP sensor. Replaced it, and no issues since. If you suspect your sensor, just swap it out and see if it fixes the problem.

34

Good to know, Sarah. Was it expensive to replace the MAP sensor?

35

Not at all! It cost me about $40 for the part, plus 30 minutes of my time. Totally worth it.

36

I keep getting P2227 intermittently. Has anyone else dealt with it coming and going? I’m starting to think it could be related to weather fluctuations.

37

I have a similar issue! Maybe check the wiring for the MAP sensor. I found a frayed wire that caused intermittent issues before.

Thanks for the tip! I’ll check my wiring next. Any advice on tools I might need for that?

39

A multimeter is super handy for checking continuity in the wiring. You might also need some basic hand tools, like pliers and a screwdriver.

I’ve never had mechanical issues until I got the P2227 code. Talk about a bad hair day for my car! Any funny stories behind this code?
