Component Description The heated oxygen sensor 2 (rear), after three way catalyst (Manifold), monitors the oxygen level in the exhaust gas on each bank. Even if switching characteristics of the heated oxygen sensor 1 (front) are shifted, the air fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2 (rear). this sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1 V in richer conditions to 0 V in leaner conditions. Under normal conditions the heated oxygen sensor 2 (rear) is not used for engine control

WARNING: Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in personal injury. WARNING: Fuel in the fuel system remains under high pressure even when the engine is not running. Before working on or disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved. Failure to follow these instructions may result in personal injury. 1. Disconnect the battery ground cable (14301). For additional information, refer to Section 414-01. 2. Relieve the fuel pressure. For additional information, refer to Section 310-00A (Gasoline) or Section 310-00B (Natural Gas). 3. Disconnect the fuel lines. For additional information, refer to Section 310-00A (Gasoline) or Section 310-00B (Natural Gas). 4. Remove the throttle body (9E926). For additional information, refer to Throttle Body in this section. 5. On gasoline engines, remove the EGR valve to exhaust manifold tube (9D477). For additional information, refer to Section 303-08. 6. Remove the drive belt (8620). For additional information, refer to Section 303-05. Vehicles equipped with natural gas engines 7. Disconnect the fuel temperature sensor connector. 8. Disconnect the fuel pressure sensor connector. All vehicles 9. Disconnect the main fuel shut-off solenoid connector. 10. Disconnect the generator cable, electrical connector, and harness pin-type retainer. 11. Remove the bolts and the generator mounting bracket (10153). 12. Remove the bolts. 13. Unclip the accelerator cable (9A758) and the speed control actuator cable (9A825) from the two crash brackets and position out of the way. 14. Separate the LH heated oxygen sensor and the transmission electrical connector from the bracket at the rear of the cylinder head. 15. Separate the fuel charging wiring pin-type retainer from the crash bracket. 16. Remove the wiring bracket. Disconnect the wiring connectors. Separate the transmission harness from the stud.
