Brothy Posted December 17, 2013 Share Posted December 17, 2013 My 1993 N\A supra has just uncounted a fault in the first time of me owning the vehicle, ive just done the paper clip blink test and the blink read out the following - 1...2...1...3...4...2 but I cant seem to find such fault code, any help will be appreciated Link to comment Share on other sites More sharing options...
Kirk Posted December 17, 2013 Share Posted December 17, 2013 That looks like 3 different fault codes. 12, 13, 42. What are the symptom's? None starter? Link to comment Share on other sites More sharing options...
Brothy Posted December 17, 2013 Author Share Posted December 17, 2013 the car runs fine, it only came on during driving and goes off after several minutes. then back on etc :/ Link to comment Share on other sites More sharing options...
Kirk Posted December 17, 2013 Share Posted December 17, 2013 Code 12 is to do with crankshaft angle and engine speed. Code 13 just confirms code 12 (momentary loss of signal) and code 42 is a fault with number 1 speed sensor. Link to comment Share on other sites More sharing options...
Brothy Posted December 17, 2013 Author Share Posted December 17, 2013 so fault 42 ( no1 speed sensor could cause the crankshaft angle fault to ? Link to comment Share on other sites More sharing options...
Kirk Posted December 17, 2013 Share Posted December 17, 2013 (edited) If the ecu is receiving a different signal from either sensor it will flag a fault. From my experience it's never been the speed signal at fault its been the distributor air gap not set correctly or the wiring to the distributor. Clear the codes and run it for a day or two and see if they reappear. They might just be old stored codes. EDIT: I misread your response, the speed sensor your referring to is in the gearbox, that's the code 42. The code 12 is separate issue and not related to crank angle/position. I will add though that code 42 won't every turn on the check engine light. Edited December 17, 2013 by Kirk (see edit history) Link to comment Share on other sites More sharing options...
Swampy442 Posted December 17, 2013 Share Posted December 17, 2013 Code 42 is a gearbox fault. Link to comment Share on other sites More sharing options...
