Honda 16400-RN0-A01 Throttle Body, Electronic Control (Gmc1E)

To replace the throttle body, remove the air intake duct, disconnect the electrical connectors, and clamp off the coolant hoses. Disconnect all hoses, disconnect the accelerator and cruise control cables, and detach the wiring harness clip. Remove the mounting bolts and nuts, discard the old gasket, and clean the bore. Install the throttle body with a new gasket, check the coolant level, and adjust the accelerator cable. Perform the PCM idle learn procedure and check for air and coolant leaks.

Take the negative battery cable connection loose. Tighten the clamps on the two coolant hoses as close as possible to the throttle body. If you do not have the right tools, just drain engine coolant keeping it below the throttle body level. Remove the air intake duct. Unplug the wiring connection that attaches to the MAP sensor. Unplug the electrical connection for the throttle body. Pull off the two coolant hose connections from the throttle body, with a rag handy to catch any leftover coolant in the hoses or body. To remove the throttle body from its position on top of the manifold, take out both bolts holding the body to the manifold and the two nuts attaching it to the upper intake. First, get rid of both the throttle body and the gasket that goes between them. Installation is the reverse of removal. Plug the terminal to the battery's negative side, start the engine, and make sure no air or motor oil flows out. After cleaning everything up, look at the coolant and pour in more to match the right amount.

Follow these steps for cleaning and preparation:1. Clean old gasket material: Clean off all old gasket material from the throttle body, spacer, and intake manifold. Ensure surfaces are smooth and free from debris.

Remove the air intake duct, disconnect the electrical connectors from the throttle body, clamp off the two throttle body coolant hoses and then disconnect them, disconnect all hoses from the throttle body, disconnect the accelerator cable from the throttle cam and the bracket, disconnect the cruise control cable from the throttle cam and the bracket, detach the wiring harness clip from the small bracket on the throttle body, remove the two throttle body mounting bolts and the two mounting nuts and remove the throttle body, remove the old throttle body gasket and discard it, remove all traces of old gasket material from the gasket mating surfaces of the throttle body and the intake manifold, spray the bore with carburetor cleaner or some other suitable solvent and thoroughly clean the bore, particularly the area below the throttle valve, by wiping off the oily residue, varnish or carbon deposits with a clean shop rag, install the throttle body with a new gasket and tighten the throttle body mounting bolts and nuts to the torque listed in the specifications, check the coolant level and top it up if necessary, check the accelerator cable adjustment and adjust it if necessary, perform the PCM idle learn procedure, check for air and coolant leaks.
