I was driving my car earlier today and had no issues at all. Stopped and filled up with gas, and proceeded to my destination, which was about 60 miles away from my house. Parked, and went and did my thing. Came back about 3 hours later, started my car up and went to leave. A few seconds after, every maintenance light came on, CEL, and a display saying "Emissions System Problem, avoid high speeds and see a dealer"

There was no lag, misfire, limp mode, or anything like that. I didn't have the use of my ACC, or LKA. Drove the car with extreme caution home with no issues at all. Idles just fine, nothing out of the ordinary.

Plugged in my OBD2 scan tool and the code P101A popped up, but nothing specific was under it.

It has a brand new battery, and the oil is changed everytime I hit the 15% mark under the maintenance option in the dash control.

I checked for a recall, but nothing had popped up when I entered my VIN.

Anyone else run into this issue? Its a 2018 Accord Sport 1.5L, 6 speed manual, 96K miles. Im trying to avoid the dealership as I cant afford that kind of expense at the moment. Can the P101A code be deciphered through a more advanced scan tool to determind the actual issue?

 

DTC P101A: Variable Valve Timing Control (VTC) B Advance Malfunction

The variable valve timing control (VTC) system controls the phase of the intake camshaft and exhaust camshaft. It uses oil pressure to operate the VTC actuator B so the valve timing is optimized depending on driving conditions. The powertrain control module (PCM) monitors the phase control command value and the actual phase value of exhaust camshaft using the camshaft position (CMP) sensor B. When an over-retarded camshaft phase angle, which the over-retarded angle is predetermined value greater than the commanded values, continues to exist while the VTC is either active or inactive or a retarded phase angle of the exhaust camshaft is greater than the predetermined value while the VTC is inactive, a malfunction is detected and a DTC is stored.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

• VTC actuator B abnormal retarded phase angle
• VTC oil control solenoid valve B stuck

 

Where would I find the VVT Solenoid on the motor? Trying to read up on it and it looks like there may be 2, but I cant seem to find where they are physically

 

VTC oil control solenoid valve B is located on the cylinder head. It may not be due to the solenoid though.

 

I appreciate it so much! Im going to test the solenoid first and see if thats where the issue lies, it not then Ill have to go down another avenue and do some digging.

Ill keep updating as I find out more/fix it

 

I really appreciate how you explain it so well by using pictures and labels. More power to you. Now I am happy I will learn so much with you guys.
