O2 Sensor Ma Reading Negative
O2 Sensor Ma Reading Negative - I would replace your fuel filter and check your fuel pressure regulator. Open the main menu on your scanner, and select “diagnose”. Web the negative reading continues with the engine switched off and the sensor heater sustained by an external battery, so it seems as though either the sensor port is blocked and contaminated or the sensor element is poisoned. In the “diagnostic menu”, tap the “data stream” icon. Compare the coolant sensor reading with the intake air temperature sensor reading on your scan tool when the engine is cold. This allows you to see how fast the voltages will go up and down.
An a/f sensor signal increasing from 0 to positive tells the ecu that the combustion contains more oxygen and is therefore considered lean, and to resolve this more fuel has to be added. Perhaps your pump is marginal. B1s2 is sitting at a. I welcome your ideas for how to solve this problem. Web tigris99 suggests that it is likely 1 of 2 problems for honda's:
