Electrical problem
1995 Ford Ranger 6 cyl Two Wheel Drive Manual 158665 miles

I have a 95 Ranger XLT ext cab 3.0L (EEC-V). The engine light was on so I took it to Advance and they read the codes.
P0340 Camshaft Position Sensor A Bank 1 Circuit Mal.
P0135 02 Sensor Heater Circuit Mal Bank 1 Sensor 1
P0141 02 Sensor Heater Circuit Mal Bank 1 Sensor 2
P0155 02 Sensor Heater Circuit Mal Bank 2 Sensor 1
I replaced all the parts and the engine light stayed off when I reconnected the battery and went for a drive. The next day the light was on again, I went to another Auto store and had them read the codes. Same codes! I told them I just replaced the parts and they reset the codes for me. It was again fine until I turned off the truck and turned it on again. The odds of all these parts being bad is small. Plus the truck does run better since I put them in. Why is the engine light coming back on?

My guess is you have a lack of power to the oxygen sensor circuit. Check for chaffed wires and follow the harness up from the sensors as far as you can.
