i got code 54 on my ITR
which is CKF Sensor (Crankshaft Speed Fluctuation) defective circuit or unplugged / defective sensor
anyone knows how to fix this?
basically car starts fine but when in gear.. i can't throttle more than half way or else car will die.. what should i do ppl??

 

what ecu are you using? I get a code 54 only from obd2 usdm ecus. if you have an obd1, or jdm ecu try it instead since neither of them look for the CKF.
