some 2000-2002 model year Nissan Sentra vehicles equipped with the 1.8 liter engine and some 2002-2003 model year Nissan Sentra vehicles equipped with the 2.5 liter engine may have a defect which relates to motor vehicle safety. The engine might stop running while being driven due to contamination of the Engine Control Module (ECM) by the inner lining material. This may also result in the “Service Engine Soon” light coming on or poor driveability. If the engine stops running while driving, this could result in a crash without warning. SERVICE PROCEDURE Remove/discard the Foam from the inside of the ECM Case Holder as follows. The ECM Case Holder will have to be re-positioned (moved) to do this procedure. NOTE: • Use suitable covers to protect vehicle paint, trim, etc. when doing this procedure. • Step one (below) only applies to vehicles equipped with a Strut Tower Cross Bar. • Doing step one will allow clearance for removing the ECM Case Holder from the engine room wall. 1. If equipped, re-position the Strut Tower Cross Bar and remove the Strut Tower Cross Bar Mounting Bracket as follows: a. Remove the nut/bolt that holds the Strut Tower Cross Bar to the Strut Tower Cross Bar Mounting Bracket (see Figure 1). b. Reposition the Strut Tower Cross Bar UP and OUT of the way. c. Take off three Nuts and remove the Strut Tower Cross Bar Mounting Bracket (see Figure 2). 2. Remove two Screws that hold the Main Wiring Harness Support Bracket to the Strut Tower (see Figure 3). 3. Disconnect the Rubber Vent Tube from the ECM Case Holder (see Figure 4). 4. If equipped, remove two Screws and re-position the Manifold Absolute Pressure (MAP) Sensor (see Figure 5). 5. Re-position the Throttle Cable Guide by removing it from the Metal Tab (see Figure 5).

Description This bulletin provides information related to the Throttle Position Sensor (TPS) for Sorento & Sedona models. Some Sorento & Sedona vehicles may exhibit diagnostic trouble codes P0121 and/or P1121. This condition mainly occurs in high ambient or desert areas, and can be related to the occasional increase in contact resistance due to excessive wear of the inner elements of the TP sensor. This bulletin describes the proper service and adjustment procedure for replacing the TP Sensor. – Service Procedure Replacement Procedure: 1. Turn ignition OFF. Remove engine cover and disconnect electrical connector from TP Sensor. 2. Remove two (2) retaining screws from TP Sensor and remove from throttle body. 3. Install new TP Sensor to throttle body. Install retaining screws and hand tighten lightly. Adjustment will be required. Re-install electrical connector to TP Sensor.

Automatic Transaxle 2-3 Shift Flare During First Minutes of Driving After Cold Soak (Perform Bulletin Procedure) Models: 2002 Saturn S-Series Vehicles with Automatic Transaxle (RPOs MP6, MP7) Attention: General Manager, Fixed Operations Manager, Parts Manager, Technician Condition: Some customers of 2002 S-series vehicles with MP6 or MP7 automatic transaxles may comment on a 2-3 shift flare during the first few minutes of driving after vehicle cold soak. Cause: This condition may be caused by improper pressure, a leak in the 2nd clutch circuit, improper clutch plate finish on 2nd and 3rd clutches, a restriction in the 3rd clutch oil delivery path in the end cover, or improper surface finish in the piston bores of the 2-3 clutch housing. Correction: To correct this condition, duplicate by cold soaking the vehicle the amount of time at temperature described by the owner. Refer to procedure in this bulletin. Service Procedure Verify proper transaxle pressures by installing gauge and performing stepped pressure test after cold soak. Refer to “Stepped Pressure Test” procedure in the 2002 Saturn S-Series Automatic Transaxle Service Manual. ^ If pressures are low, follow the diagnostic chart for DTC P0745 for possible causes of low pressure. Refer to “P0745 – PC Solenoid Pressure Low” diagnostic in the 2002 Saturn S-Series Automatic Transaxle Service Manual. ^ If pressures are within normal ranges, proceed to Step 2. Remove the transaxle end cover. Refer to “End Cover Replacement” in the 2002 Saturn S-Series Automatic Transaxle Service Manual. Check torque on input shaft nut and end cover 3rd clutch oil passage for restrictions. ^ Input shaft nut torque should be 150 N.m (111 ft-lb). If nut is found to be loose, remove nut, clean threads and install new nut using Service Manual procedures and proceed to check 3rd oil passage. ^ Check 3rd oil passage in the end cover by pouring transaxle fluid through it and another passage. If the passage is restricted, you will notice significantly less fluid flow through it. If 3rd clutch passage is found to be restricted, install new end cover per Service Manual procedures and retest for concern. ^ If nut and 3rd clutch passage are okay, proceed to Step 4. Remove transaxle from vehicle. Refer to “Transaxle Removal” in the 2002 Saturn S-Series Automatic Transaxle Service Manual. Disassemble transaxle and install new 2-3 clutch housing, clutch pistons and clutch plates. Refer to “Transaxle Disassemble” in the 2002 Saturn S-Series Automatic Transaxle Service Manual.
