Re: Milano/75 questions

[Howard and Pat Warren <warrenwood@domain.elided>]

Joe asked a couple of Milano questions:

<<<<<
First, the oil level sensor has died and constantly indicates low oil on 
the ARC. As I don't trust these devices anyway I'm not too keen on buying a 
new sensor. Does anyone know how to trick the ARC into ignoring this sensor 
- - shorting it or leaving the connector off is  not the answer.
>>>>>

You've posted a question with contradictory answers.  First, the assumption 
the oil level sensor is untrustworthy really is false.  The sensor is not 
particularly expensive, around $30~50, but installing it is a PITA.  Still, 
I only replaced the level sensor on my Milano once in 165k miles.

Second, you ask how to "trick" the ARC into ignoring the sensor, but 
without shorting the sensor.  Unless you're prepared to reprogram and 
reburn the logic chips of the ARC, this is not possible (to my knowledge.) 
 The oil level logic expects voltage continuity from the sensor.  To fake 
out the continuity, the wire must be grounded (iow, shorted.)

Personally, I would replace the sensor.

<<<<<
Second, when driving in excess of 70 mph and then decerlerating to a speed 
less than 70 I get a momentary oscillation in the speedometer needle 
(magnitude +/-10 mph) as the needle passes the 70 mark. Otherwise the 
speedo is fine.
>>>>>

I would suspect a signal problem.  The speedo sensor is in the transaxle. 
 Decelerating through 70 MPH, do you feel any vibration or shimmy?  If so, 
the signal wire could be loose.  Otherwise, I would just watch it and wait 
for it to get worse.
