I plugged my OBD 2 scanner into the plug on my 1995 B4000 SE 4x4 4.0 OHV
I got these codes:
P0500 Vehicle Speed Sensor A Malfunction
P0141 O2 sensor Heater Malfunction B1 S1
P0155 O2 sensor Heater Malfunction B2 S1
P1151 Lack of upstream heated O2 sensor _______switch; indicates lean bank 2 (Ford specific code)
P0401 EGR flow insufficient
so question 1:
Supposedly my truck is not OBD 2 compliant. But it has these codes. So why is that???
Question 2: does anyone have experience repairing these issues on this vintage Ranger or B-4000???
(my speedometer has never worked since I’ve owned the truck; is that due to the speed sensor malfunction?)
