Sensor refers to the sensor mounted in front of the Three-Way Catalytic Converter (TWC) and located near the engine assembly. DCRIPTION The /F sensor generates a voltage * that corresponds to the actual air-fuel ratio. This sensor voltage is used to provide the ECM with feedback so that it can control the air-fuel ratio. The ECM determines the deviation from the stoichiometric air-fuel ratio level, and regulates the fuel injection time. If the /F sensor malfunctions, the ECM is unable to control the air-fuel ratio accurately. The /F sensor is the planar type and is integrated with the heater, which heats the solid electrolyte (zirconia element). This heater is controlled by the ECM. When the intake air volume is low (the exhaust gas temperature is low), a current flows into the heater to heat the sensor, in order to facilitate accurate oxygen concentration detection. In addition, the sensor and heater portions are narrower than the conventional type. The heat generated by the heater is conducted to the solid electrolyte though the alumina, therefore the sensor activation is accelerated. In order to obtain a high purification rate of the carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide (NOx) components in the exhaust gas, a TWC is used. For the most efficient use of the TWC, the air-fuel ratio must be precisely controlled so that it is always close to the stoichiometric level. * : Value changes inside the ECM. Since the /F sensor is the current output element, a current is converted in to a voltage inside the ECM. ny measurements taken at the /F sensor or ECM connectors will show a constant voltage.

DTCs P97 and P98 indicate malfunctions related to bank /F sensor circuit. Bank refers to the bank that includes cylinder No.. Bank refers to the bank that includes cylinder No.. When any of these DTCs are set, check the /F sensor voltage output by selecting the following menu items on an intelligent tester: DIGNOSIS / ENHNCED OBD II / DT LIST / PRIMRY / FS BS or FS BS. Short-term fuel trim values can also be read using an intelligent tester.

3 3 GR-FE ENGINE CONTROL SYSTEM SFI SYSTEM The ECM regulates the voltages at the +, +, - and - terminals of the ECM to a constant level. Therefore, the /F sensor voltage output cannot be confirmed without using an intelligent tester. If a /F sensor malfunction is detected, the ECM sets a DTC. MONITOR DCRIPTION Sensor voltage detection monitor Under the air-fuel ratio feedback control, if the /F sensor voltage output indicates rich or lean for a certain period of time, the ECM determines that there is a malfunction in the /F sensor. The ECM illuminates the MIL and sets a DTC. Example: If the /F sensor voltage output is less than.8 V (very rich condition) for 0 seconds, despite the HO sensor voltage output being less than 0.6 V, the ECM sets DTC P96. lternatively, if the /F sensor voltage output is more than 3.8 V (very lean condition) for 0 seconds, despite the HO sensor voltage output being 0.5 V or more, DTC P95 is set. Sensor current detection monitor rich air-fuel mixture causes a low /F sensor current, and a lean air-fuel mixture causes a high /F sensor current. Therefore, the sensor output becomes low during acceleration, and it becomes high during deceleration with the throttle valve fully closed. The ECM monitors the /F sensor current during fuel-cut and detects any abnormal current values. If the /F sensor output is 3.6 m or more for more than 3 seconds of cumulative time, the ECM interprets this as a malfunction in the /F sensor and sets DTC P95 (high-side stuck). If the /F sensor output is.57 m or less for more than 3 seconds of cumulative time, the ECM sets DTC P96 (low-side stuck). ir Fuel Ratio Sensor Current Monitor Cumulative Time "t" = t + t =3 seconds or more Fuel-Cut ON OFF Delay (3 seconds) Delay (3 seconds) Delay (3 seconds) Sensor Current (m) High Side Threshold Low Side Threshold 3 seconds or more t t Normal Sensor Output bnormal Sensor Output Time 0765E0

(b) Turn the ignition switch ON. (c) Turn the tester ON. (d) Clear DTCs (See page -38). (e) Start the engine, and warm it up until the ECT reaches 75 C (67 F) or higher. (f) Select the following menu items to check the fuel-cut status: DIGNOSIS / ENHNCED OBD II / DT LIST / USER DT / FC IDLE. (g) Drive the vehicle at between 38 mph (60 km/h) and 75 mph (0 km/h) for at least 0 minutes. (h) Change the transmission to nd gear.

9 38 GR-FE ENGINE CONTROL SYSTEM SFI SYSTEM (i) Drive the vehicle at proper vehicle speed to perform fuel-cut operation (refer to the following HINT). Fuel-cut is performed when the following conditions are met: ccelerator pedal fully released. Engine speed is,500 rpm or more (fuel injection returns at,000 rpm). (j) ccelerate the vehicle to 40 mph (64 km/h) or more by depressing the accelerator pedal for at least 0 seconds. (k) Soon after performing step (j) above, release the accelerator pedal for at least 4 seconds without depressing the brake pedal, in order to execute fuel-cut control. (l) llow the vehicle to decelerate until the vehicle speed declines to less than 6 mph (0 km/h). (m) Repeat steps from (h) through (k) above at least 3 times in one driving cycle. Completion of all /F sensor monitors is required to change the value in TT RULT. CUTION: Strictly observe posted speed limits, traffic laws, and road conditions when performing these drive patterns. Malfunctioning areas can be identified by performing the /F CONTROL function provided in the CTIVE TT. The /F CONTROL function can help to determine whether the ir-fuel Ratio (/F) sensor, Heated Oxygen (HO) sensor and other potential trouble areas are malfunctioning. The following instructions describe how to conduct the /F CONTROL operation using an intelligent tester. () Connect an intelligent tester to the DLC3. () Start the engine and turn the tester ON. (3) Warm up the engine at an engine speed of,500 rpm for approximately 90 seconds. (4) Select the following menu items: DIGNOSIS / ENHNCED OBD II / CTIVE TT / /F CONTROL. (5) Perform the /F CONTROL operation with the engine in an idling condition (press the RIGHT or LEFT button to change the fuel injection volume). (6) Monitor the voltage outputs of the /F and HO sensors (FS BS and OS BS or FS BS and OS BS) displayed on the tester. The /F CONTROL operation lowers the fuel injection volume by.5 % or increases the injection volume by 5 %. Each sensor reacts in accordance with increases and decreases in the fuel injection volume.

To display the graph, select the following menu items on the tester: DIGNOSIS / ENHNCED OBD II / CTIVE TT / /F CONTROL / USER DT / FS BS and OS BS or FS BS and OS BS, and press the Y button and then the ENTER button followed by the F4 button. Read freeze frame data using an intelligent tester. Freeze frame data record the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data, from the time the malfunction occurred. low /F sensor voltage could be caused by a rich air-fuel mixture. Check for conditions that would cause the engine to run rich. high /F sensor voltage could be caused by a lean air-fuel mixture. Check for conditions that would cause the engine to run lean. CHECK NY OTHER DTCS OUTPUT (IN DDITION TO P95, P96, P97 OR P98) (a) Connect an intelligent tester to the DLC3. (b) Turn the ignition switch ON. (c) Turn the tester ON.

(e) Select the following menu items: DIGNOSIS / ENHNCED OBD II / SNPSHOT / MNUL SNPSHOT / USER DT / FS BS or FS BS and ENGINE SPD. (f) Check the /F sensor voltage three times, when the engine is in each of the following conditions: () While idling (check for at least 30 seconds) () t an engine speed of approximately,500 rpm (without any sudden changes in engine speed) (3) Raise the engine speed to 4,000 rpm and then quickly release the accelerator pedal so that the throttle valve is fully closed.

(This will also happen if the /F sensor heater has an open circuit.) If the output voltage of the /F sensor remains at either approximately 3.8 V or more, or.8 V or less (see Malfunction Condition diagram) under any conditions, including those above, the /F sensor may have a short circuit.

13 3 GR-FE ENGINE CONTROL SYSTEM SFI SYSTEM The ECM stops fuel injection (fuel cut) during engine deceleration. This causes a lean condition and results in a momentary increase in the /F sensor output voltage. The ECM must establish a closed throttle valve position learning value to perform fuel cut. If the battery terminal has been reconnected, the vehicle must be driven over 0 mph (6 km/h) to allow the ECM to learn the closed throttle valve position. When the vehicle is driven: The output voltage of the /F sensor may be below.8 V during fuel enrichment. For the vehicle, this translates to a sudden increase in speed with the accelerator pedal fully depressed when trying to overtake another vehicle. The / F sensor is functioning normally. The /F sensor is a current output element; therefore, the current is converted into a voltage inside the ECM. Measuring the voltage at the connectors of the /F sensor or ECM will show a constant voltage result.
