How to Service the Throttle Position Sensor on Mercury Mariner?

CTP sensor service requires operatives to start by disconnecting the TP sensor electrical connector and battery ground cable. The service of the TP sensor begins by removing its two mounting screws and extracting the sensor piece. The installation process requires screw tightening to 10 Nm (89 lb-in) and performing the removal steps in reverse order to finish the task.

How to Properly Handle the Throttle Position Sensor on a Mercury Grand Marquis?

Service of the throttle position (TP) sensor starts with disconnecting the electrical connector. A hand tool should first loosen the TP sensor screws 1-2 full turns before the use of a suitable high-speed driver to prevent damaging the screws. bioswabs should absorb the discarded TP sensor together with its two screws. Installation should utilize both fresh TP sensor components and screws because replacing old equipment is forbidden. Set the radial locator tab on your new TP sensor to the radial locator hole on the throttle body before putting the sensor in place and screwing on two new screws that need to be tightened to 3 Nm (27 lb-in). Complete the process by reattaching the TP sensor electrical connector.

How to properly maintain the Throttle Position Sensor on a Mercury Marauder?

The service procedure for the throttle position (TP) sensor begins by taking out the battery ground cable. The service of idle air control (IAC) sensor and TP sensor requires disconnecting their electrical connectors. Unfasten the bolts which secure the IAC sensor and afterward extract the sensor from its position. The first step requires removing the bolts connected to the TP sensor while also taking out the TP sensor. Simply do the opposite steps used for removal to install back.
