What is the sixth letter of the GY6 engine code?
The sixth letter thereafter is code for engine displacement size measure in “cc” (cubic centimeter). See the table below. Notice as each alphabetical order B-to-Y so is the engine displacement CC increases incrementally 10cc, 15cc, 25cc, 50cc, and 100cc.
What does the code p0016 GMC stand for?
P0016 GMC Meaning The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, 6 of which are equally spaced 60 degrees apart.
Where is the engine code on a GY6 scooter?
GY6’s engine code is located on the lower side of CVT, just beside the oil drain bolt. The first set of numbers above is the scooter engine code. The secondary number below is the engine’s unique identification numbers (engine registration numbers).
What does ” 39 ” Mean on a GY6 engine?
Another example: if it was a 139QMB the “39” would mean that it has a 39mm piston with a cylinder outer skirt of 44.78mm, which may vary by manufacturer slightly off by 0.2mm, allow it slip into the 139QMB engine’s crankcase bore opening 52.5mm max.
What is the diagnostic code for a GM V6?
Crankshaft position (CKP)/Exhaust camshaft (CMP) correlation Bank 1 (RH) This code points to a misalignment between the exhaust camshaft on bank 1 and the crankshaft. Most probable cause is one or more stretched timing chains – Most likely being the bank 1 sub chain.
What to do if diagnostic code P008 is not present?
If codes P008 and P0009 are not present, you will need to connect factory equivalent scan tool to monitor camshaft position on the affected bank. You must then actuate the correct VVT solenoid with engine at idle. If idle does not change significantly, you likely have a VVT solenoid failure.
What is an OBD-II trouble code on a car?
What is an OBD-II Trouble Code? On-Board-Diagnostic (OBD) trouble codes are one way your vehicle communicates with a mechanic.

What does the OBD2 code p0016 Mercedes mean?
OBD2 Code P0016 Mercedes definition: The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.
