| Jan 14, 2023 at 15:20 | comment | added | amphibient | @Pᴀᴜʟsᴛᴇʀ2 -- after I cleaned the old sensor and replaced the air filter, the CEL went away but only for 150 mi and then it came back. So because the sensor is only about $26 with shipping, I ordered a new one. But here is a question: when I install it, should I reset the CEL (erase the code) and wait for it to perform the engine sensor testing from 0 or should I leave it as is and see if the CEL will go away? | |

| Dec 10, 2022 at 20:20 | comment | added | amphibient | is that similar to BlueDriver? I used my buddy's bluedriver and it didn't give me those detailed statistics | |

| Dec 10, 2022 at 18:19 | comment | added | amphibient | @HandyHowie -- i have a "stupid" OBD2 that only reads codes. any recommendation for a more sophisticated one that reads engine params ? | |
| Dec 10, 2022 at 18:19 | comment | added | amphibient | this seems to have fixed the problem | |
| Dec 9, 2022 at 15:39 | comment | added | jwh20 | Before buying anything check the wiring carefully. Note that in some vehicles there may be more than one connector that fits. So you may have the MAF wire switched with some other wire. | |
| Dec 9, 2022 at 8:57 | comment | added | HandyHowie | Use an OBD reader to read the live values from the MAF. You should be able to get it to draw a live graph. Check if the graph looks something like expected. | |
| Dec 9, 2022 at 3:29 | comment | added | amphibient | yeah, makes sense, except I don't know any "donor". I just cleaned the MAF sensor with the special spray and also replaced the air filter, which did look kinda bad on a second look | |
| Dec 9, 2022 at 2:08 | comment | added | Pᴀᴜʟsᴛᴇʀ2♦ | @amphibient - Before you buy a new sensor, see if you can find a "donor" from some other vehicle to check. Before you buy anything, always know that what you're purchasing is actually needed. A new MAF may not be the ticket, but it sure looks like it from here. | |

| Dec 8, 2022 at 23:47 | comment | added | amphibient | so basically, if cleaning the sensor does not clear the code, buy a new sensor, correct? | |
