SYMPTOM When the engine is first started after the vehicle has sat overnight, customers may “feel” the release of the throttle plate through the accelerator pedal. Some describe it as a one-time “pop” sensation. Customers may have trouble explaining this phenomenon because: They can’t repeat it because it only happens one time, when the engine is cold. The accelerator pedal works normally at all other times. There are no other symptoms. It may be intermittent, happening only during cooler weather. PROBABLE CAUSE The symptom is caused by normal buildup of contaminants in the throttle bore, combined with expansion and contraction of the throttle body. CORRECTIVE ACTION Partially remove the throttle body, and clean it with Honda carburetor cleaner or throttle plate and induction cleaner. REPAIR PROCEDURE 1. Remove the breather tube from the air intake duct, unclip the vacuum lines from the duct, and remove the duct from the throttle body. See Fig. 1 . Fig. 1: Removing Air Intake Duct 2. Disconnect the TPS and MAP connectors from the throttle body. 3. Remove the throttle cable and, if equipped, the cruise control actuator cable from the throttle body. 4. Remove the throttle body mounting nuts and bolts, then slide the throttle body off its studs on the intake manifold chamber. Leave the coolant hoses connected. See Fig. 2 . 5. Put a shop towel under the throttle body, open the throttle, then clean out any contaminants from the intake manifold side of the throttle body with carburetor cleaner or throttle plate and induction cleaner. See Fig. 3 . NOTE: To avoid damaging the idle air control valve (IACV), spray the cleaner through the back of the throttle body, not the front.

ISSUE Some 2005-2009 Escape Hybrid and 2006-2009 Mariner Hybrid vehicles may exhibit an intermittent Red Triangle On and Stop Safely Now message displayed on the message center accompanied by a sudden RPM loss/no start symptom with a diagnostic trouble code (DTC) P1A0C. Vehicles may exhibit this symptom on the first start of the morning or after an extended idle. The symptom will clear on the next key cycle. ACTION Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE For vehicles outside the new vehicle limited warranty, if diagnostics lead to replacing the throttle body you may use this procedure to clean the throttle body as an alternative to replacing it. This procedure is not covered by the new vehicle limited warranty. NOTE THIS CLEANING PROCEDURE CAN ONLY BE USED ON NON-COATED THROTTLE BODIES. Refer to Workshop Manual, Section 303-04C Removal and Installation – Throttle Body. 1. Remove the throttle body. 2. With the throttle body positioned to the side, open the throttle plate. 3. Using Motorcraft® Choke and Linkage Cleaner or equivalent, spray the throttle body plate and bore. 4. Using a suitable (nylon) brush, clean the edges of the throttle plate and the mating surface of the throttle bore to remove all carbon build up. 5. Reapply Motorcraft® Choke and Linkage Cleaner or equivalent and wipe clean with a lint-free cloth. 6. Remove old throttle body gasket and discard. Install a new throttle body gasket. 7. Install the throttle body.
