ES
HINT:
• Although the DTC titles say the oxygen sensor, these DTCs relate to the Air-Fuel Ratio (A/F) sensor.
• Sensor 1 refers to the sensor mounted in front of the Three-Way Catalytic Converter (TWC) and
located near the engine assembly.
DESCRIPTION
Refer to DTC P2195 (See page ES-355).
HINT:
• When any of these DTCs are set, the ECM enters fail-safe mode. The ECM turns off the A/F sensor
heater in fail-safe mode. Fail-safe mode continues until the ignition switch is turned off.
• The ECM provides a pulse width modulated control circuit to adjust the current through the heater. The
A/F sensor heater circuit uses a relay on the +B side of the circuit.

(b) Lightly press the valve face against the valve seat.
(c) Check the valve face and valve spring seat by using
the following procedure:
(1) If Prussian blue appears around the entire
valve face, the valve face is concentric. If not,
replace the valve.
(2) If Prussian blue appears around the entire
valve seat, the guide and valve face are
concentric. If not, resurface the valve spring
seat.
(3) Check that the valve spring seat contacts in the
middle of the valve face with the width between
1.1 and 1.5 mm (0.043 and 0.059 in.).
22. INSPECT EXHAUST VALVE SEAT
(a) Apply a light coat of Prussian blue to the valve face.
(b) Lightly press the valve face against the valve spring
seat.
(c) Check the valve face and valve spring seat by using
the following procedure:
(1) If Prussian blue appears around the entire
valve face, the valve face is concentric. If not,
replace the valve.
(2) If Prussian blue appears around the entire
valve seat, the guide and valve face are
concentric. If not, resurface the valve spring
seat.
(3) Check that the valve spring seat contacts in the
middle of the valve face with the width between
1.1 and 1.5 mm (0.043 and 0.059 in.).
23. REPAIR INTAKE VALVE SEAT
NOTICE:
• Repair the seat while checking the seating
position.
• Keep the lip free of foreign matter.
(a) Using a 45
cutter, resurface the valve spring seat
so that the valve spring seat width is more than the
specification.
