Top 10 1998 Cadillac Catera Questions & Answers

Hi mike and melissa, you can go to gmownercenter/cadillac and sign up at the website, u can then download a owners manual which should have the fuse info u want, and much more. Let me know if u have any trouble finding it. Happy Thanksgiving!

You need to have it checked out by a mechanic as soon as possible, I drive a 2000 cadillac catera and it began to have the same problems about 4 months ago but last month my sport mode button began to blink which means a transmission problem. So when i had it looked at they said my 3rd gear was almost completely burnt out and it cost $2,000 to fix. The cause was a broken piece of the transmission was failing and it had to be completely rebuilt. Good luck!!

The problem is in the stoplight switch. It is located under the dash. When you push the brakes, the switch contact points close. When you let off the brake, the open, turning the brake lights back off. Also your cruise will not work if it is getting a signal that the brake pedal is being pushed.

You can get one from the dealer or on ebay.
I would recommend an aftermarket unit with car starter. Much cheaper, 2 remotes and starts the car as well.

tu problema no eran las cabezas sino un enfriador de aceite que se esncuentra en medio del motor por debajo del multiple de admision lo puedes identificar por las dos lineas gruesas que se le conectan, su funcion es enfriar el aceite del motor pero hay defecto de fabrica y la agencia te repone el motor gratuitamente o puedes comprar la refaccionen la agencia la cual viene perfeccionada por el precio de 350dll

El problema está en el enfriador de aceite, que va instalado el el bloque del motor, justo en medio de las cabezas.
Cambiando el enfriador de aceite se resulve el problema. El # de parte es 93176626 y lo puedes comprar en www.rockauto.com el precio es de USD 235

The upstream oxygen sensor is typically found on the exhaust manifold that is bolted to the engine block. It may be as far up on the exhaust as the the manifold piping located in the front of the engine under the hood. The sensor looks like a plug sticking out of the exhaust piping and will be the only plug inserted into the exhaust system.

Important:

Removal of the oxygen sensor is easier when the engine temperature is above 48CC

(120T).

' Handle the oxygen sensors carefully in order to prevent damage to the component.

Keep the electrical connector and the louvered end free of contaminants. Do not use

cleaning solvents on the sensor. Do not drop or mishandle the sensor.

REMOVAL

Numbers in ten in parenthesis correspond to numbered components in image.

1. Raise and support the vehicle.

2. Disconnect the sensor harness connector.

3. Remove the oxygen sensor.

Bank 1 Sensor 2(1)

Bank 1 Sensor 1(2)

A Bank2Sensorl(3)

A Bank2Sensor2(4)

INSTALLATION

Important: A special anti-seize compound is used on the oxygen sensot threads. The new

service sensors should have the compound already applied to the threads. Coat the

threads of a reused sensor with anti-seize compound P.N 5613695 or the equivalent.

1. Install the oxygen sensor.

Bank 1 Sensor 2(1)

A Bank sensor (2)

A Bank2Sensorl (3)

A Bank2Sensor2 (4)

Important: Make sure that all of the harness retaining clips are intact. The harness

must not contact any of the hot exhaust components. The HO2S pigtail has white

tape at the intervals, indicating the proper location of each retaining clip. When

connecting the sensor pigtail to the harness, ensure that the connector seal is

crushed uniformly all the way around between the connectors.

2. Connect the sensor harness connector.

3. Lower the vehicle

304 is misfire on cylinder #4. #4 is the middle cylinder on the driver's side.
The other 2 relate to the crankshaft sensor:

P0335 Crankshaft position (CKP) sensor -

possible causes: circuit malfunction Wiring, CKP sensor, ECM

P0336 Crankshaft position (CKP) sensor - range/performance problem
possible causes: insecure sensor/rotor, air gap, wiring, CKP sensor

Is the car running? If yes, check for a loose connector on the crank sensor. You may need to take the connector off and see if there is any corrosion on the terminals. If yes, do your best to clean with a small screwdriver and/or electrical parts cleaner.

From what I can tell, the sensor is on the bottom of the engine near the idler arm, but it has a long pigtail such that the connector is on top of the engine by the fuel rail. See pictures below.

for the misfire,

Please see my tip at http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

el problema de aceite mescandose con el anty congelante es por lo regular empaques de cabeza pero en algunos casos puede ser solo empaques de manifool de admission o en terminos usuales diriamos empaques de la arana asegurese que el mecanico le de un precio en caso de que solo sean los empaques de arana por logica seria mucho mas varato que los de cavezas. el caso de la cantada a que se devio le faltava agua? o estava tirando talves bueno a menos que la transmission no trabajava bien antes de la primer calentada estaria en mal estado pero si trabajo bien antes no tendra ningun problema. espero este comentario le ayude para ahorrar algo de dinero y trabajo buena suerte, informeme de lo que acontesca y grasias.
