I got a 99 Ex coupe auto , in the last 8 months I have replaced about 3 TPS's. I put them all on correctly, checked them with a mutlimeter, after 2-3 months I get code 7 ... any suggestions?

 

does it have a high idle, if so u may want a new throttle body cuz i had that problem with the spring which can be replaced but i decided to buy a new tb and it worked

 

You didnt flip the TPS and MAP sensor plugs right....?

 

no my idle is fine, and I did not swith the map with tps, its happened 3 times in the last 8 months, it just happens out of the blue like today I get code 7 cel

 

check your connectors could be a faulty one!

 

which ones?
btw I got it scanned and this is what I get
P0122 Throttle Position (TP) Sensor Circuit Low Input

 

I had the little pins inside the plug get corroded and do that. The springy part corroded completely away, causing an intermittent connection. I grabbed some pins from my cruise control plug and put them in the TPS plug, no problems since.

 

maybe u have a short in 1 of the wires
