Faulty A/F Sensor Can
Cause Multiple DTCs
A faulty A/F sensor in a ’03–05 MDX or ’04–05 TL
can cause any or all of these DTCs to set:
• DTC P0134 [rear A/F sensor (bank 1, sensor 1)
heater system malfunction]
• DTC P0154 [front A/F sensor (bank 2,
sensor 1) heater system malfunction]
• DTC P2237 [rear A/F sensor (bank 1, sensor 1)
IP line high voltage]
• DTC P2240 [front A/F sensor (bank 2,
sensor 1) IP line high voltage]
To fix this problem, check the sensor wiring and
connections for damage. If the sensor circuit is
OK, and the DTC(s) come back after clearing
them and doing a short test-drive, replace the A/F
sensor. The replacement A/F sensors in Honda
parts stock are an improved version over the
original sensor. bank 1 located at rear engine by firewall.
