Hi i have a 1996 accord ex 2.2 lt vtec with a automatic transmission. Im getting error codes p0141 o2 sensor heater circut malfunction ( bank 1 sensor 2) where can i find this sensor?


I also have error code p0501 vehicle speed sensor A range/performance what is this and how can i fix it?

A few months ago my speedometer stopped working everything else on the cluster still works so i changed the speed sensor and the speedometer still doesnt work is there another sensor? Any advice on how to fix this?

Any advice would help Thanks

 

B1-S2 is the O2 sensor behind the catalyic converter.

Since you've replaced the VSS, you may have wiriing or connector damage causing loss of speedometer function. Are the odometers and cruise control not working? This would confirm the gauge panel is not getting a good VSS signal somehow.

Inspect wiring and connectors (trace wiring) and look for possible damage. You can disconnect from VSS and gauge panel and check individual wires and connections w/ VOM by shorting one end to ground and checking other end for ground. If ground is missing you've found the damaged or open wire.

If all looks OK, you can attach a voltage monitor to the VSS output and monitor for voltage outputs when wheel is rotated manually. It should show a on/off/on... voltage pulse of several volts.

good luck

 

Thanks for the info and quick response
