What Does Code P2227 Mean for My Chevy Cruze?

Questions and Support
1

I’m currently facing an issue with my Chevy Cruze, and I’m hoping to get some insights from anyone who’s dealt with this before. I’ve come across the diagnostic trouble code (DTC) P2227, and I’m trying to figure out what it signifies and how to address it.

What is Code P2227?

From what I’ve gathered, code P2227 usually relates to the Manifold Absolute Pressure (MAP) Sensor and the Barometric Pressure Sensor range/performance problem. This code is specific to Chevy models, including the Cruze, and it usually indicates that the readings from these sensors are not within the expected parameters of the vehicle’s computer.

Possible Causes

A few things could potentially trigger this code:

  • Faulty MAP or Barometric Pressure Sensor: The sensors themselves might be defective.
  • Wiring Issues: Look for damaged wiring or poor connections between the sensors and the engine control unit (ECU).
  • Vacuum Leaks: A leak in the intake manifold or any vacuum hoses can cause misleading pressures.
  • ECU Problems: Sometimes the issue might not lie with the sensors but rather with the vehicle’s computer.

Symptoms to Look For

Besides the check engine light turning on, here are some symptoms you might experience:

  • Rough idle or stalling
  • Decreased fuel efficiency
  • Unusual engine behavior
  • Increased emissions output

Troubleshooting Steps

  1. Check for Codes: If you have an OBD-II scanner, clear the codes after writing them down and see if they return.
  2. Inspect the Sensors: Take a close look at the MAP and barometric pressure sensors for damage or corrosion.
  3. Examine the Wiring: Make sure there’s no fraying or broken wires affecting the sensors’ readings.
  4. Look for Vacuum Leaks: Use a smoke test or carburetor cleaner to help identify any leaks in the intake system.
  5. Consult a Professional: If you’re not finding any issues or if you’re not comfortable troubleshooting, it might be best to consult a mechanic who has experience with Chevys.

Repair Guides

If anyone has helpful links to repair guides or insights on how they fixed this issue on their Cruze, I would greatly appreciate your input! I’m eager to hear from those who’ve been through this and can share their experiences, repairs, or any tips that could help. Thanks in advance for any advice you can provide!

Exactly! It feels like your car is on a roller coaster ride. What steps did you take to fix it?

6

I replaced the intake air temperature sensor, and it cost me about $100. It’s not too complicated if you’re handy with basic tools.

7

That’s good to know! How long did it take you to do the job?

8

It took me about an hour. Make sure you have a torque wrench on hand! You don’t want to over-torque anything.

9

I’m wondering if P2227 could also lead to any long-term damage if ignored? I want to avoid any costly repairs down the line.

10

It’s definitely best to address it sooner rather than later. Ignoring it can lead to further issues like reduced performance or even damage to the engine over time.

11

That makes sense. I don’t want my car to be a performance potato!

12

Great advice! I had a friend who ignored their check engine light, and it cost them a ton to fix. Think of it as a warning to save your wallet!

I feel a bit overwhelmed with all this info. Is there a quick checklist for symptoms to watch for with P2227?

16

I recently encountered code P2227 on my Chevy Cruze. From what I understand, it usually indicates an issue with the barometric pressure sensor. Has anyone else had this problem?

17

Yes! I had the same issue, and it turned out to be a faulty sensor. Replacing it solved the problem for me.

18

This code can indeed be related to sensor issues, but don’t overlook the wiring. Corroded or damaged wires can also trigger P2227. Check those first!

19

I had no idea wiring could cause this! That’s good to know. It seems like you really have to check every possibility with these codes.

What specific wiring issues should we look for? I’m not very familiar with electrical systems.
