Herein, what does j1850 VPW mean?

J1850-41.6 - Ford The SAE J1850.41.6 standard refers toFord'scommunication protocol. This protocol has been used by Fordsince1996. With Ford's protocol, each bit of information is 24 uslongand has variable voltage pulse widths to represent a logic 0 or1.This is referred to as Pulse Width Modulated(PWM)system.

what obd2 protocol does Ford use? SAE J1850 VPW: This obd2 protocol isusedby Ford. SAE J1850 PWM: Common Motors utilizethisprotocol. ISO 9141-2: You will find this protocolonAsian, Chrysler, and European cars. ISO 14230 KWP2000:Thisprotocol is found in Asian vehicles.

Similarly, you may ask, what is obd2 CAN protocol?

OBD2 is a 'higher layer protocol' (thinkofit as a language) while CAN bus is a method forcommunication(like a telephone). Since 2008, CAN bus (ISO15765) has beenthe mandatory protocol for OBD2 inall cars sold inthe US, which basically eliminates the other 4protocols overtime.

What data is available from OBD?

OBD-IIoffers a standard way to access many types ofdata,including: Real-time parameters: RPM, speed, pedalposition, sparkadvance, airflow rate, coolant temperature, etc.Status of“Check Engine” light.
