2001 Honda Civic Q&A
2001 Honda Civic Question: I need to Replace Evaporative Emissions (EVAP) Control System Pressure Sensor.
why are you changing it? do you have an eng code or light on? - globalhelper
Replace the FUEL TANK PRESSURE SENSOR underneath car with canister and two-way valve. THEN when the check engine light comes back, diagnose circuit as globalhelper suggested. NORMAL value with cap off is 2.5V kill mouse that chewed wires or vacuum hose. - ziptie12
