How to turn off CEL that came on when the heater control was replaced?

Many Highlanders have a heater control problem as I've discovered per Web discussions. A wire or wires loosen in the assembly and need re-soldering. When I pulled the heater control knob to check its stability per Web instructions, (while the car was running) the CEL came on. I've fixed the heater control ... how to I extinguish the CEL?

You cannot turn off the CEL without a scan tool.

1997 Mazda Protege...CEL P0141 still on with both new o2 sensors.


Code 141 is for the heater circuit for bank one sensor two. That is the O2 sensor after the catalytic converter.
If you have replaced the sensor and the code still sets, the problem is in the harness or the power source for that heater circuit.
The sensor is taking too long to heat up.

Hi my 1999 1.8T beetle has CEL p0116 and P1196. I've tried fixing my P0116 problem which is temp sensor coolant range per. I've replaced my faulty blue sensor (the square one) with the new green sensor....


P1196=Oxygen Sensor Heater Circuit,Bank1-Sensor1 Electrical Malfunction,
this is the exhaust on the drivers side,and the O2 sensor before the converter.

P0116=ECT, this is the Engine Coolant Temperature switch,NOT the temperature sending unit.

Air cond goes from cold to hot on coldest setting or if its on hot it will start blowing cold


You have a broken wire on the heater control potentiometer. You can either order and replace the control, which is expensive, or you can remove the control, and disassemble it, and re-solder the broken wire. We do this all of the time; resolder the pots bacjk on to the main PC board.
