“I recently changed my Mass Airflow Sensor in my 2008 cry because I had a code p0113, now that the new sensor is in, im getting a p0171. I read that the new sensor might not be calibrated with the ECM and that disconnecting the battery for 20 minutes might fix it, but i dont know how true that is.”View original

“Doing research online I found that this is often the VTEC solenoid. I replaced this, cleared the code, and after about 30 mins of driving it came back (and goes into limp mode with a triangle/VSA light as well).”View original

“I replaced this, cleared the code, and after about 30 mins of driving it came back (and goes into limp mode with a triangle/VSA light as well). I am selling the car for my mom, and trying to figure out if there is another more inexpensive thing to try, or if I should just take a drastically lower price to sell as is.”View original
