Remove the engine cover first. Then, disconnect the electrical connector from the MAP sensor. Proceed to remove the MAP sensor bolt and pull the sensor from the upper intake manifold. Installation is simply the reverse of removal. It's important to use a new MAP sensor O-ring seal, and lubricate it with a little clean engine oil.

Check the condition of the grommet and replace if necessary for 2004 and earlier models. Replace the sensor if the seal is damaged for 2005 and later models. Installation is the reverse of removal.

To remove the sensor from the charge air cooler cover, simply remove the mounting fasteners.

Remove the old grommet from the MAP sensor and inspect it. If the grommet is cracked or torn, replace it.

Installation is the reverse of removal.

Squeeze the clip ends together to disconnect it.

The MAP sensor on V6 models is located on top of and at the left rear corner of the intake manifold. To remove the MAP sensor from the intake manifold on a V6 engine, disconnect the electrical connector, remove the retaining bolt, remove the hold-down clamp, then pull the sensor straight up. Next, remove the MAP sensor retaining bolt and the hold-down clamp, then remove the MAP sensor. Remove and inspect the old MAP sensor sealing grommet. If it's cracked, torn or otherwise deteriorated, replace it. When installing the MAP sensor, use a little clean engine oil on the grommet so that it doesn't tear when pushing the MAP sensor into its mounting hole. Installation is the reverse of removal. For V8 models, the MAP sensor is located on the intake manifold, right behind the throttle body. Start by removing the engine cover. Then, disconnect the MAP sensor electrical connector by prying up the locking tab on the connector, then pull the sensor straight up while wiggling it side to side. Pull the sensor straight up to remove it. Remove and inspect the old MAP sensor sealing grommet. If it's cracked, torn or otherwise deteriorated, replace it. When installing the MAP sensor, use a little clean engine oil on the grommet so that it doesn't tear when pushing the MAP sensor into its mounting hole. Installation is otherwise the reverse of removal.

To remove the 2.4L MAP sensor, start by removing the engine cover and then disconnect the air cleaner outlet duct from the throttle body. Next, disconnect the electrical connector to the sensor and remove the mounting bolt and the sensor from the intake manifold. For installation, simply reverse the removal steps. For the 3.4L MAP sensor, begin by disconnecting the electrical connector and removing the bolt and hold-down bracket to detach the sensor from the upper intake manifold. To install, follow the reverse of the removal steps and ensure to use a new o-ring and tighten the hold-down bolt securely. For the 2013 and later 3.6L MAP sensor, remove the engine cover and disconnect the electrical connector from the sensor located on top of the intake manifold. Then, remove the sensor mounting bolt and pull the sensor from the manifold. To install, reverse the removal steps and remember to use a new o-ring and tighten the hold-down bolt securely.

To remove the MAP sensor on a V6 model, you need to disconnect the electrical connector and then pull the sensor straight up out of the intake manifold.

To remove the MAP sensor on a V8 model, you first need to remove the intake manifold cover. Then, disconnect the electrical connector before removing the sensor retainer. Finally, pull the sensor straight up to remove it.

The TMAP sensor is located at the right end of the intake manifold.

To install, reverse the removal steps and remember to use a new o-ring and tighten the hold-down bolt securely.
