my 2001 with over 200 thousand miles honda civic Lx engine 1.7. i got the codes 132 and 137 i know the 132 is
P0132 Primary Heated Oxygen Sensor (Primary HO2S) (Sensor 1) Circuit High Voltage
and code 137 is
P0137 Secondary Heated Oxygen Sensor (Secondary HO2S) Circuit Low Voltage

i have changed both oxygen sensors, and cleaned the connectors, the connectors was oil soak from an oil leak but i used alchol and cleaned both them

now within 10 miles i got the code P0131 could the oil on the connectors caused this and maby i didnt get them cleaned?

 

go to an auto parts store and buy some cnc electric parts cleaner spray the connectors with it and try it again. also fix your oil leak!!
