I recently purchased a slightly salvaged TSX. The car does not start and it has a bunch of messages on the Dash when the key is turned. The DTCs I am getting are as follows:

P0108 MAP/BARO Circuit High Input
P0974 Shift Solenoid A Control Circuity High
p0986 Shift Solenoid E Control Circuity High

I wanted to find out if any one knows which Solenoid is which. I looked at a diagram located at http://estore.honda.com/EPC/images/p.../SDA3A0710.png

Number 6 in the Diagram shows some physical damage but no other Solenoids show any damage. I would like to know what Solenoid on that diagram is A and which is E. Does anyone have any insight into the First DTC P0108.

Finally the Display Screen on the the Dash read as folows:

Check Tire Pressure
Check VSA
Check Transmission
Check Emission

I know what the Tire pressure is about. I guess the Transmission has to do with the solenoids, and the Emission message probably has something to with the fact that the cat-back of the car is ripped off. I am not sure what the VSA is all about. Thanks for any help.

 

FWIW none of the components in your picture are shift solenoids. #6 is the Linear Solenoid which controls varies clutch line pressure to control shift "harshness". The five shift solenoids are mounted internally in the trans and are accessed through a cover on the lower front of the trans.

I'd recommend you invest in a proper service manual for the car. It will likely take some good old fashioned diagnosis to fix this car (as is often the case with "salvaged" vehicles).

 

... that's just about every error you can get O_O

 

Thanks I was under the impression those where the solenoids I had to get repaired as they show physical damage. I guess I will start by replacing the damaged linear solenoid and also replacing the whole wire harness. A lot of the main harness is damaged. The wire coming of #8 in the diagram is damaged which is the shift solenoid I believe you are talking about as that is covered on the lower front of the Trans. Just want to make sure both solenoids I mentioned are the ones you say are covered in the front of the trans. I have already purchased a pretty good manual on eBay, this thing covered a lot. I planning on buying the helms manual as I had one for my 99 TL and it was great but the eBay TSX manual was pretty comprehensive.

 

Good luck with the repairs! Sounds like you have quite a bit on your plate.

 

What's the history of this car? It sounds like a can of worms best left unopened.
