DTC P0153 (2014 2015 2016 2017)

DTC P0153: Front Air/Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) Malfunction/Slow Response

General Description

Courtesy of HONDA, U.S.A., INC.

The front air/fuel ratio (A/F) sensor (bank 2, sensor 1) has a linear signal output in relation to the oxygen concentration. The powertrain control module (PCM) computes the air/fuel ratio from the front A/F sensor (bank 2, sensor 1) output voltage and uses fuel feedback control to improve exhaust emissions. The PCM compares the response characteristics against the front A/F sensor (bank 2, sensor 1) output. If the total front A/F sensor (bank 2, sensor 1) output is a specified value for a specified time, the PCM detects a deteriorated response and stores a DTC.

Confirmation Procedure

Operating Condition

Courtesy of HONDA, U.S.A., INC.

1.
Start the engine. Hold the engine speed [ENGINE SPEED] at 3000 RPM without load (in P or N) until the radiator fan comes on.
2.
Drive the vehicle at a steady speed of 25 mph (40 km/h) or less, for at least 5 minutes.
3.
Drive immediately at a steady speed of 36 mph (57 km/h) or more and engine speed [ENGINE SPEED] between 1500 - 2500 RPM*1 (1250 - 2500 RPM)*2 for at least 6.8 seconds.

Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

With the HDS

None.

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
