I am doing check engine light diagnosis on my 2015 Nissan Sentra. Here the ODB Scanner Report
Based on report - It says MAF sensor wiring (it might be bad) I have tested my MAF sensor wiring by starting the car and unplugging the wire. If the engine shuts down, then there is no problem with the wiring. For my case Engine has shut down as soon as wiring has removed. Not a wiring issue [I have come to know this via YouTube] correct me if am wrong or share me a DIY video of how to check this.
And as a Standard safety check earlier few days back there was issue sensor, facing sudden acceleration issues (even though no force applied gas petal). I cleaned it with an airflow cleaner. then on highway drives, check engine light has gone off.
So, this time i have also cleaned my airflow sensor.
Another thing this report says is about Cam shaft sensor bad, but based on my research if that sensor goes bad, for my car the car won't even start until sensor has been replaced & cleared the code. In my case my car starts fine & runs smoothly.
Another thing to look at it has controller area Network line malfunction - it means it has issue with ECM and ECM needs to be reprogrammed something like that [This is something only Nissan dealers can do it. and fairly expensive]
Any suggestions on how to proceed further, just worried if this minor issue can be high cost later. Do I need to take this to the Nissan mechanic for diagnosis because it might require ECM reprogramming. check engine light is ON for more than 2 months now.
If the fix is simple, then it doesn't make spending too many bucks for that. And doing DIY might be ideal
Note: I have noticed few changes like engine running high RPM on idle, its a bit more lound than usual and drop in fuel economy. And I feel for high RPM - throttle body cleaning is required. and for engine performce - engine oil might needs to be changed
