code 51
 

I have an 89 yota pickup, with a 3.0L, auto, 4x4. it is currently refusing to idle. the CEL is blinking a code 51 at me. does anybody know what code 51 means other than something to do with a switch signal? i.e. which switch or how to fix it?

a/c switch,circuit,or amplifier. t.p.s switch,or sensor. ecu

yup, you could also google it, i found a few responses that way.

from the sounds of it, check your tps
