Hyundai 2000 Accent P1123

Question

Car sat for 5 months before purchase. Was driven prior to this with CEL on codes unknown

Answer 1

2000 hyundai accent does not use codes p0027,  p0059 and p0091 in the service manual

p0123 is related to the throttle position sensor, I would clean the throttle body and the sensor first before replacing parts

 

p1123 might be related to p0123 so fix that issue first
