P010B



P0101, P010B MAF SENSOR



Description



The mass air flow sensor (1) is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow.



The mass air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wire is reduced as the intake



air flows around it. The greater air flow, the greater the heat loss.



Therefore, the electric current supplied to hot wire is changed to maintain the temperature of the hot wire as air flow increases. The

REMANUFACTURED ENGINE LUBRICATION UPON INITIAL START UP



APPLIED VEHICLE:



All Infiniti vehicles having a remanufactured engine installed



SERVICE INFORMATION



During remanufactured engine storage, upper engine lubrication may dissipate/disperse. Camshaft scoring or seizure may occur at initial start up



unless the procedure below is followed.



1. Refer to the MA section of the applicable Electronic Service Manual (ESM) to determine the specified volume of oil required to fill both the



crankcase and filter.



2. Set one (1) quart of oil aside and fill the crankcase with the remaining quantity (one quart should remain unused).



3. Prior to initial engine start up, pour the one (1) remaining quart of oil into the valve cover.



^ It is recommended to quickly squeeze the quart of oil out of the container to "flood" the camshafts and cam bearings.



Page 212



4. Immediately start the engine while the upper end is "flooded" with oil.

Is the inspection result normal?



YES - INSPECTION END



NO - Replace crankshaft position sensor.



P0340



P0340, P0345 CMP SENSOR



Description



The camshaft position (CMP) sensor senses the retraction of camshaft (INT) to identify a particular cylinder. The camshaft position sensor senses



the piston position.



When the crankshaft position sensor system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead,



utilizing timing of cylinder identification signals.



The sensor consists of a permanent magnet and Hall IC.



When engine is running, the high and low parts of the teeth cause the gap with the sensor to change.



The changing gap causes the magnetic field near the sensor to change.



Due to the changing magnetic field, the voltage from the sensor changes.



ECM receives the signals as shown in the figure.

NOTE:



If DTC P0340 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. See: P Code Charts/P0643.

P0122



P0122, P0123, P0227, P0228 TP SENSOR



Description



Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle



valve movement.



The throttle position sensor has two sensors. These sensors are a kind of potentiometer which transform the throttle valve position into output



voltage, and emit the voltage signal to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and controls



the throttle valve opening angle in response to driving conditions via the throttle control motor.

^ Recent design changes have been made to the Tire Pressure Monitoring System (1PMS) sensor receiver and control units (new style TPMS



components).



^ These changes were applied as follows:



Page 281



^ These changes do not affect the overall function of the TPMS.



^ These changes do affect the interchangeability of parts. For example:



> Full wheel assemblies (wheel and tire assemblies with TPMS) cannot be swapped between old style sensor-equipped and new style



sensor-equipped vehicles.



CAUTION:



^ New style and old style TPMS components are not compatible and cannot be interchanged.



^ Swapping of new style and old style components will cause the TPMS to stop operating correctly.



If further confirmation of the TPMS sensor part number is required review the part number of the originally installed equipment before replacement.



To confirm the latest part numbers, always consult the appropriate parts catalog when replacing or exchanging TPMS sensors, receivers, or control



modules.



NOTE:

Description



The engine coolant temperature sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the ECM. The



modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in



temperature. The electrical resistance of the thermistor decreases as temperature increases.

U1000 CAN COMM CIRCUIT



Description



CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with



high data communication speed and excellent error detection ability. Modern vehicle is equipped with many electronic control units, and each



control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are



connected with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less wiring. Each control



unit transmits/receives data but selectively reads the required data only.

P1550



P1550 BATTERY CURRENT SENSOR



Description



The power generation voltage variable control enables fuel consumption to be decreased by reducing the engine load which is caused by the



power generation of the generator. The battery current sensor is installed to the battery cable at the negative terminal. The sensor measures the



charging/discharging current of the battery. Based on the sensor signal, ECM judges whether or not the power generation voltage variable control



is performed. When performing the power generation voltage variable control, ECM calculates the target power generation voltage based on the



sensor signal. And ECM sends the calculated value as the power generation command value to IPDM E/R. For the details of the power generation



voltage variable control, See: Starting and Charging/Charging System/Description and Operation.



CAUTION:



Never connect the electrical component or the ground wire directly to the battery terminal. The connection causes the malfunction of the



power generation voltage variable control, and then battery discharge may occur.
