Hi I have a 1994 Ford Ranger with the 2.3 and it is giving me these codes (key on, engine off). Can someone point me in the direction I should go to fix it?
539 (O) System shows voltage at PCM pin 10. Is A/C on (it was on)
181 (M) Fuel system was lean at part throttle Single, Right or Rear HO2S
223 (M) Dual Plug (DPI), SPOUT or IDM circuit fault
224 (M) Failure in ignition coil primary circuit
452 (M) Vehicle Speed Sensor (VSS) problem
Thanks so much
