First thing to remember autozone people ar not experts in the automative diagnostic world, if they were they would be earning 50 - 75,ooo per year as a technician, not 25,000 as a desk jockey. You need to go to a mechanic that has a computer to hookup to your car and tell you what the check engine light is on for. then you can fix the exact problem instead of poking around in the dark at the problem until you get lucky and have it fixed for a week or two,

The P1700 is just a request for the check engine light, and this is caused by the U2108. The U2108 is basically telling you that the Electronic Brake and Traction Control Module (EBTCM) is not communicating with the powertrain control module, or the transmission control module.
The very first thing we must do is verify that the fuses that power the ebtcm are not blown and that they are powered. At this point I would like you to verify that the fuse labeled ABS in the fuse block is not blown and that it is powered with the key in the on position.
I would also like you to verify that the fuse labeled V1 inthe power distribution box is not burnt and that this is powered also. After this we need to move to the ebtcm to verify that you have voltage at pins 15,17,18 and that you have a ground at 19 and 16.

This would verify that the ebtcm is getting the proper voltage supplies to operate. The end result of this may possibly be a faulty ebtcm, but at this point we really need to check these items prior.Feel free to contact me with any questions at this point! Thanks!

P0440 - Check Gas Cap to be sure it is tight and not leaking air. Possibly just replace it.

P0410 - Secondary Air Injection system. Typically the check valve near the firewall goes bad. There is also one on the driver's side near the radiator. Could also be a fuse for the fan or the fan itself. The fan/blower is tucked under the left front fender - remove the wheel well liner to get to it. This is an emissions code only and will not effect the operation of the car. The check valves are roughly $200.00/ea. A lot of people choose not to fix this code.

first i would have autozone give you a print out of the codes that were stored in the computer of your cars ecm.then check the trouble tree for diagnosing those codes.autozone sells a book on trouble codes.do you have over 100,000 miles on the car? the converter is covered upto 10 years or 100,000 miles.next, yes you can remove and replace the 02 sensor,with a 7/8 wrench and or buy a 02 socket.on a 4 cyl. engine there is 2 one before and one after the converter which is located in the exhaust close to the engine.hope this helps.

Dear Williammoody,

I saw your advice to terry69jam on Sep 26, 2009.

I have the same error code p1750 which shows up as "Mechanical Problem in Hydraulic Control System of A/T Clutch Pressure Control Solenoid." Your initial recommendation to terry69jam is replacing a tranny. Was your later suggestion on replacement of the shift solenoid can be made in lieu of replacing a tranny? Does "pack" mean the shift solenoid? If yes, where can I find a replacement and how much would that cost?
