Remarks
[1] Full rich condition.
[2] CO: Carbon monoxide, is a sign of incomplete ignition, (not enough oxygen to burn all the hydrocarbons in cylinder).
[3] O2: Oxygen left over after all hydrocarbons have been burned.
[4] Full lean condition.
[5] Stoichiometric point: Output voltages below 0.45 volts indicate a lean condition, and output voltages over 0.45 volts indicate a rich
condition.
NOTE: Both lean and rich conditions are usually accompanied by high Hydrocarbon (HC) readings. Due to not enough fuel, (lean misses), or too much
fuel, (not enough oxygen to burn all hydrocarbons).
