This code came back when "service engine" light came on - 2002 X terra - anyone had any experience with this?

i dont know maby you are ridding the clutch..... maby it has some burnt plates.... havent a clue

i dont really understand it but i found this by inputing you title into google.....

an overrunning clutch control valve (http://www.patentstorm.us/patents/4881429-claims.html#);

a shuttle valve, said shuttle valve being fluidly communicated with said source of pilot (http://www.patentstorm.us/patents/4881429-claims.html#) pressure, said shuttle valve being arranged to control the supply of pilot pressure to said overrunning clutch control valve, said shuttle valve being operatively connected with said solenoid solenoid valve in a manner wherein when said solenoid valve is conditioned to assume said first state said shuttle valve modifies the supply of pilot pressure to said overrunning clutch control valve and induces line pressure to be supplied to said second clutch via said overrunning clutch control valve;

said overrunning clutch control valve being operatively interposed between said second clutch and said shuttle valve.

here is the link to that page...... http://www.patentstorm.us/patents/4881429-claims.html
