OBDII UART Fuel system status

Post by matinzk »

Hi,

How can I get the status of the following?

0x03 - Fuel system status

Mode 1 PID 03
A request for this PID returns 2 bytes of data. The first byte describes fuel system #1.

Value Description
1 Open loop due to insufficient engine temperature
2 Closed loop, using oxygen sensor feedback to determine fuel mix
4 Open loop due to engine load OR fuel cut due to deceleration
8 Open loop due to system failure
16 Closed loop, using at least one oxygen sensor but there is a fault in the feedback system

Any help is appreciated.

Thank you.
