For Civic or Integra models, begin by removing the console and unplugging the 14-pin connector from the gear position switch. Detach the switch by removing the mounting nuts, then adjust the switch by sliding it toward the Drive positions until continuity is established between the specified terminals within the shift lever freeplay range. Recheck continuity to ensure the engine starts in the Neutral position; if not, inspect the shift lever detent and bracket for damage, replacing the switch if necessary. For CR-V models, apply the parking brake and place the shift lever in Neutral, then check that the gear position indicator illuminates when the ignition is on. Raise the vehicle securely on jackstands, remove the cover from the gear position switch, and loosen the mounting bolts to adjust the switch until the indicator lights up, tightening the bolts afterward. For replacement in Civic and Integra models, follow similar steps to remove the old switch, ensuring the new switch is positioned correctly at Neutral before securing it and testing functionality. In CR-V models, unplug the electrical connector, remove the switch, and check for any leakage around the transaxle control shaft before installing the new switch in the Neutral position, ensuring the indicator lights up before finalizing the installation.
