Thanks for the correction.
Sorry for but now I really don't understand this rule.
Other existing sensors, excluding the stock air metering device, may be substituted for equivalent units.
Equivalent - The same form, fit, function, and dimensions.

So I can replace a sensor, say a coolant temp sensor, with an alternate, but it must be the same form, fit and dimensions as the OEM sensor? So it must have the same shape, it must screw into the same hole, it must use the same connector, it must have exactly the same dimensions. I cannot belive that was the intent of the rule. Especially since "equivalent" wasn't in the glossary when the rule was written. I think the glossary entry added this year totally changes this rule.
