Suddenly lots of codes	Sign In

Have a 2000 ford ranger xlt with a 4cyl. I've had it since new and currently has 356000 miles so I've gotten my use out of it. It Ran fine until today with no codes showing, although maybe the light is out, because the light still doesn't show. It starts fine and runs fine at low rpm's starts breaking up as I step on the gas. throwing codes 125, 1451, 135, 141, 1409, 172.

P0125 Insufficient coolant temperature for closed loop fuel control

P1451 EVAP Control System Canister Vent Solenoid Circuit Malfunction

P0135 O2 Sensor Heater Circuit (Bank 1 Sensor 1)

P0141 O2 Sensor Heater Circuit (Bank 1 Sensor 2)

P0172 System Too Rich (Bank 1)

P1409 P1409 - EVR Control Circuit Malfunction

You have a few circuit codes in there. You might want to start by checking power to the O2 sensors' heater circuits, the canister vent valve, and the EGR vacuum regulator valve. You should see battery voltage to those items with the ignition on. Check the PCM HEGO (fuse 13) 15 amp in the battery junction block. It might be blown. If it is blown, one of those componets or their circuits is shorted and causing excessive amounts of current to blow out the fuse.

Thanks
The fuse was blown. I cleared the codes and have driven about 100 miles around town and none have come back yet.

That fuse did blow for a reason, so you might have some type of intermittent short going on.
