This procedure only applies to V6 models from 2008 and earlier, as the Neutral Safety Switch on 2009-on models is inside the transaxle valve body, and should be done by a qualified technician or repair facility. In order to perform this procedure, a special tool (manufacturer tool no. 307-351 or equivalent) is required. Failure to use this tool will result in the switch not being adjusted correctly, resulting in trouble codes and driveability issues. If the special tool is not available, you should have the procedure performed by a dealer service department or other qualified repair shop. To begin, set the parking brake and place the shift lever in Neutral. Take out the battery and battery tray, and then you will have to remove the air filter housing and air intake duct. Drain the engine coolant and take off the thermostat housing. The Neutral Safety Switch can be disconnected by removing the electrical connector; remove the mounting bolts and unscrew the switch. To install the switch, install the special tool on the switch, ensuring that the prongs engage with the notches in the rotating ring. Put the switch onto the transaxle and rotate the ring on the switch so that projections align with slots on the shaft. Once the switch mounting bolts are installed and tightened, remove the special tool and reconnect the connector. The rest of the installation is done in reverse order. Upon battery reconnection and a system coolant refill, the Powertrain Control Module (PCM) needs to relearn idle and fuel trim strategy for maximum driveability and performance.
