i recently purchased a 1992 si 4ws. i too had a cel light come on and jumpered the blue plug to find a code 29. noshoaccord were you getting a code 29 or a code 62 cel?(code 62 is fixed by resoldering the 2 relays in the control unit) after doing the full diagnosis per the honda repair manual, i found that the culprit is the rear main steering angle sensor! so noshoaccord, i was wondering what came of your call to the honda dealership on this matter? im about to go and purchase a new sensor from majestichonda.com for 140, or get the entire actuator and gear + sub sensor and rear main sensor for 100(used). i now know it is definetly a faulty sensor as the light only reappears when hard cornering. if it were the acutator in the other hand, it would be on immediatly apon turning the wheel due to contamination in the gears themselves.
let me know.
