2004 Cadillac DeVille Throttle Body Parts and Q&A

• Q: How to service the throttle body on 2004 Cadillac DeVille?

  A: Service of the Throttle Body begins with disconnecting the maf sensor electrical connector yet maintaining the screen's integrity since damage to this area can block airflow and cause driveability problems. Service professionals should disconnect the maf sensor electrical connection while loosening intake air duct clamps to extract the assembled mass air flow (MAF) sensor and air cleaner intake duct. Use the throttle valve position to check the surfaces on the Throttle Body bore and throttle valve plate. Systems using methyl ethyl ketone (MEK) should not be used as cleaning solutions because they will cause damage to fuel system parts. Use gm top engine cleaner (P/N 1052626 Canada P/N 993026) or ac-delco carburetor tune-up conditioner (P/N X66-P) or equivalent cleaning agent for clearing the Throttle Body bore and throttle valve plate with a clean shop towel. When installing the air cleaner assembly and maf sensor inlet duct should be properly aligned to stop erroneous airflow readings from triggering mil alerts and driveability problems. Connect the maf sensor alongside the air cleaner intake duct assembly before securing the intake duct clamps at 3 n.m (27 lb in) torque setting before hooking up the maf sensor cable.
