Were there any other codes? The first thing to check is the condition of the battery. A low, flat or old battery can sometimes create this code as the electronics don't have enough power to work correctly. Old batteries, often five or more years old, can be weak and not hold charge correctly.

Cadillac is the make. V8 is the engine configuration. 1.9 litre is the cubic capacity. Nnone of that is 'year make model' as needed. With torque specs, the engine has an alpha numerical number and that is useful as well. Like this; Torque Specifications for. GM 4.9L-301ci-V8 Or we can guess, hope for the best and see what happens :>D https://www.google.com/search?q=valve+train+torque+specs+on+the+4.9L+Cadillac+V8 ..

What year is your caddy ? The blend door actuator probably needs to be replaced .

The blend door is controlled by a electronically controlled motor by the CCM .

question 2, are you going to ask for ever word in the chapter cooling? stated in the manual? still posted lack the 5 engine sizes huge engine have huge transmission and need special cooling, even 2 coolers and types. ok? frankly I just look, at the side of the tranny and see 2 small METAL pipes, not rubber hoses. they go to the tranny cooler, 1 or 2. if not modified by others to say pull a trailer. full of bricks. the 1st 2 show this Disconnect the lower transaxle oil cooler line from the radiator got 5L50 trannY, for sure as cooling ATF lines. Aisin ay6? not the stick shift. Tremec 6-Speed pick one and I will read to you. power steering has and oil to air cooler. the 5L50 box here the rad connections takes a special tool to unsnap them and not wreck them. T= TO TRANNY NO TRANNY TOLD. NO ENGINE TOLD. THE VIN CODE HAS A ENGINE CODE , LOOK IT UP ONLINE 'TYPE VIN DECODER AND SEE THE ANSWER.

"Thunking" is often a suspension issue. Possibly worn bushes, linkages or ball joints. Is it a single thunk as you first pull away or several thunks as you start to roll forwards? The squealing brakes could be a separate issue. Ask a good mechanic to look at it and they can tell you what the problems are in more detail.

you dont need to and an 01 caddy is not a mandatory dealership for key most locksmiths dont have the equipment to cut and program automotive keys ---you have a transponder chip key some hardware and big box stores can cut new keys from an old one ---if no keys then needs to be cut by a dealer or an automotive authorized locksmith because need to cut by vin and key not $304 + also dont need to tow vehicle -----------

the word sensor , missing? all cars in USA 1996 up for sure have CKP sensor and 99%^ of them changed out is not cure. not scanning the PCM first is why you miss out on causes the crank sensor is in 3 places all front ,middle or rear of the crank shaft. the 3.6 L the tone wheel is on the REAR service manual shows at #8

OP you did that all wrong. the parts are NOT PNP not plug and play at all and even by LAW. those parts must be reprogrammed and remarried or IMMO will be dead.

Here's a wiring guide for the fuel pump on a 2000 Cadillac Deville: 1. Remove the fuel tank and access the fuel pump module. 2. Disconnect the electrical connector from the top of the fuel pump module. 3. Locate the wiring harness that runs from the fuel pump module to the car's electrical system. 4. Cut the wires on the old fuel pump module connector, leaving enough wire to splice the new connector onto. 5. Connect the black wire from the new fuel pump module connector to the black wire in the car's wiring harness. 6. Connect the purple wire from the new fuel pump module connector to the purple wire in the car's wiring harness. 7. Connect the gray wire from the new fuel pump module connector to the gray wire in the car's wiring harness. 8. Connect the black/white wire from the new fuel pump module connector to the black/white wire in the car's wiring harness. 9. Connect the new fuel pump module electrical connector to the car's wiring harness connector. 10. Reinstall the fuel tank. Note that it is important to follow the wiring guide carefully to ensure proper installation and avoid damaging the fuel pump or electrical system. If you are unsure about any step of the process, it is recommended to seek assistance from a professional mechanic or refer to the vehicle's service manual.

There are two easy tests for the catalytic converters. One, use a infrared pyrometer and measure the temperature of both catalytic converters and compair the readings. There should not be much difference between the two if both are flowing correctly. Another easy test is to drill a 1/4" hole before each cat and check for excessive back pressure.

The 2007 Cadillac DTS does not have an inertia fuel reset switch. Instead, it has a fuel pump relay located in the rear fuse block under the back seat. If you are experiencing a fuel system issue, you may want to check the fuel pump relay and fuse first. If these components are functioning properly, you may need to have the fuel system diagnosed by a qualified mechanic.
