- Higher than the actual liter size of the engine
- Equivalent to the liter size of the engine
A perfect lambda sensor PID reading is:*
- 200 millivolts
- 1
- 500 millivolts
- 0

Presented by Master Mechanic Ron Bilyeu and focusing on Toyota and Ford scan data, the presentation drills down deep into both prominent and obscure PIDs, explaining the valuable content they show. Information on air/fuel ratios, knock sensors, idle evaluation, misfires, VVT, and crankcase pressure measuring is only a small part of the information presented.
