EHA? I'm not familiar with that acronym.
Recently I replaced the lambda sensor. and got the Bosch
generic
version for the 126. but you loose out on the two white wire heater
connections. Originally the plug has a white dot on one pin. these heater
wire connected one way give a faster response on the diagnostic pins 2
and 3
for the duty cycle.Of course there could be variations on the USA
versions
compared to European models.
Interesting! I would never have expected a heater to be
polarity-sensitive.
