BRIEF HISTORY THAT LEAD TO PROBLEM.
Question My honda Prelude 1997 Vti-r 156-000km. ATTS light and engine light come on after i drive it for about 20 mins. this malfunction happened after i had the clutch replaced. mechanics computer tells him there ia a vss problem and that i need to have the vss sensor replaced no gurantee that its the actual problem . or is there a different issue
Answer The ATTS is a common quirk with the last generation Preludes, considering most Hondas don't have quirks!
The VSS is located on top of the tranny, if I am not mistaken, the power steering fluid hoses reside right above it, check to see if the connector is broken and or fluid may have leaked onto the sensor connector, also check the condition of the wires connecting to it to see if it is OK. The Sensor is approx. $80 and up but a VSS code 17 can be a bunch of other related problems.
I am also curious to know wether your speedometer went out as the problems occurred, that can also be a confirmation of a necessary VSS replacement.
The Preludes transmission system (SH) is a fairly complicated piece of machinery and is not your typical tranny. I would get the car diagnosed using an OBD (On Board Diagnostic) scanning tool to see if there is only one or multiple codes.
Mechanics who work on 5th Gen Preludes should be very aware of its design but if they aren't, they may inadvertently cause harm to a Preludes complicated tranny system.
The Vehicle Speed Sensor sends signals to your speedometer and the ECU in order to let the car know when to shift. When the VSS is out, the car in a sense has no idea what engine and transmission decisions to make because it does not know how fast it is going.
The bad news obviously is that the car is not running right until the problem is fixed.
I wish it were just a simple fix to have you get your car up and running but due to the complexity of the Honda ATTS system, not being there to see and take a look at problem makes it difficult for me to make an accurate judgement call.
Check to see if you're speedometer is working and then go from there.
