i have a 2000 honda civic and got in an accident recently. the front of the car was messed up got it fixed but the speedometer wasnt working and had a check engine light. when scanned got these codes. what should i do?

P0501 speed sensor/range performance
P1298 electrical load detector circuit high voltage
P0135 02 sensor heater circuit malfunction ( bank 1 sensor 1)
P0141 02 sensor heater circuit malfunction ( bank 1 sensor 2)
P1870 Manufacturer specific powertrain trouble code
P1882 Manufacturer specific powertrain trouble code

i just pulled up these codes now. i reset them and then a few minutes later the check engine light came on. I will check tomorrow to see if the same codes come up.

 

take it back where you got your car "fixed" and tell them theyre not done. those are all gunna be related to your accident

 

i just got a 2000 civic that was in a front accident too. and im pretty much getting the same codes as you.. any help on what to do?

 

Check engine light is on. Trouble codes P0500, P0135, P0141 and P1298. Fuse #15, the 7.5-amp fuse, was blown and will blow intermittently.
Tests/Procedures: 1. Check the wire harness under the intake manifold. The wire harness by the brace, or bottom of the intake manifold, will rub and short out the Black/Yellow wire and cause the fuse to blow and set all the codes.

2. There is also a factory TSB on this problem. If the wire harness is OK, try unplugging the junction connector and power each circuit separately and see what circuit the short is located on.

3. If no problem is found there, verify that the Bypass Solenoid (BS) for the evaporative system is not shorted. If that is the problem, the fuse will only blow when the Engine Control Module (ECM) runs an evaporative test and the solenoid may damage the ECM.

so check the wiring harness under the intake manifold to start, look for loose ground connections to the intake, or wiring showing exposed wiring and shorting out, if you find any damaged wires, fix them, either with solder or just butt connectors, and then replace fuse 15 and see if it comes back

 

Is 7.5A dash fuse 15 blown?

 

fixed my civic.. i believe a 7.5 fuse was blown. but i dont know which one it was. and i unplugged the airbags and reset the ecu.. only codes im getting are 14iacv and o2 sensor..
