Thank you for taking time to ask your Honda question on JustAnswer. My name is ***** ***** online handle is Honda-Man I will be assisting you. I have over 21 years experience repairing strictly Honda vehicles.

The pressure sensor used in this type of system is not an on off type switch. Older systems used a basic switch you could jump or ground without worry. The 3 wire pressure sensor connects directly to the engine control module. It's a sensitive circuit that doesn't hold up to having power applied or grounded. Basically what I am getting to is the ECM was damaged so now it can't start. You are going to need to replace the ECM and reprogram the keys(immobilizer system) before it will start. Programming needs to be done at the dealer or by a qualified locksmith or repair facility. It's not a do it yourself procedure. Sorry for the bad news, I do see this happen from time to time so don't feel bad. They should have used a fuse to protect the ECM!

What's the price range on something like that?
Customer: replied 1 year ago.
The owner, replaced the ac compressor thinking that was the problem for the ac not working. Once replace still wasn't working so he went ahead and replace the pressure switch.

Sorry for the delay. The ECU from Honda is $422. Programming it at the dealer is usually 1/2 to 1 hour labor so $50-125 depending on the shop rate. Might be able to find on cheaper online? Or send that one out for repair. There are online sites that can repair them.

Thank you,
