Make:
Mercury
Code:
U0415
Definition:
HO2S Slow Response Bank 2 Sensor 1
Description:
P0153 DTCs P0068, P0101, P0102, P0103, P0106, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0120, P0121, P0122, P0123, P0128, P0201, P0202, P0203, P0204, P0205, P0206, P0207, P0208, P0220, P0222, P0223, P0442, P0443, P0446, P0449, P0455, P0496, P1516, P2101, P2119, P2135, P2176 are not set.The Engine Coolant Temperature (ECT) Sensor parameter is more than 60°C (140°F).The Intake Air Temperature (IAT) Sensor parameter is more than -40°C (-40°F).The Ignition 1 Signal parameter is between 10-18 volts.The Fuel Level Sensor parameter is more than 10 percent.The Engine Run Time parameter is more than 160 seconds.The Engine Speed parameter is between 1,200-3,000 RPM.The Barometric (BARO) Pressure parameter is more than 70 kPa.The Mass Airflow (MAF) Sensor parameter is between 20-55 g or s.The Loop Status parameter is Closed.The Throttle Position (TP) Indicated Angle parameter is more than 5 percent.DTC P0153 runs once per drive cycle when the above conditions are met for 1 second.
Cause:
The ECM detects that the HO2S 1 rich-to-lean or lean-to-rich average response time is more than a calibrated value.DTC P0133 sets within 100 seconds when the above condition is met.
