2001 Cadillac Catera - Answered Questions & Fixed issues

There are Two temp valve actuators, a mode door actuator and a defrost/floor actuator. Are the heater hoses under the hood getting hot? You can use comment to reply. I hope this helps. Take care.

Check that all your ground wires are well attached and attaching points are clean and free of corrosion. Also check for parasitic drains such as an underhood light, trunk light, map light, floor lights, something plugged into dc outlet like a cell phone charger left plugged in, etc. is not draining your battery overnight or over time when parked.

it's the cranshaft position sensor
it's a very common problem with the catera's

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems.

It may just be a bad sensor. The pressure could be tested with a mechanical gauge, but the sensor is probably so cheap it's not worth paying a shop to do a diagnostic if you can replace the sensor yourself. If it's not a bad sensor the oil pump may be worn out, or maybe the engine bearings are worn. A thicker oil might buy you some time on it.

The 'S' you discribe must surely be the Sport Mode on light, which is turned on and off by the button on top of the shift lever. Must likely problems with a battery issue like that would probably be an alternator problem, or simply a poor electrical connection. Your best bet , take it to a qualified repair shop .

Perhaps the steering lock is on Sometimes you have to take the weight off the steering .As you try to turn the key turn the steering wheel at the same time Good Luck :)

Its on the side of the block firewall side ... REMOVAL Numbers in text in parenthesis correspond to numbered components in image. Disconnect the wiring harness (1) from the Crankshaft Position (CKP) sensor pigtail. Securely attach a scrap piece of wire about 36 inches long to the CKP sensor pigtail. Later, this piece will be used as a pull wire to guide the new sensor pigtail back through the same routing. Raise and support the vehicle. Remove the oil filter and capture any lost engine oil in a container. Loosen the oil cooler lines at the engine block. Back out the fittings far enough in order to gain sufficient clearance for the sensor pigtail connector to pass between the oil cooler lines and the side of the engine block. Remove the fastening bolt for the CKP sensor (1). Remove the CKP sensor and the O-ring seal from the engine block. Remove the CKP sensor pigtail. Observe the routing of the pigtail. Gently pull the CKP sensor pigtail down through the routing path and out. Guide the pigtail connector along the top of the oil cooler lines around to the side of the engine block. Pass the connector between the lines and the block at the point of the widest gap. Stop when the pull wire is exposed at both ends of the routing path. Disconnect the sensor from the pull wire. INSTALLATION Securely attach the CKP sensor pigtail to the lower end of the pull wire. Pass the pigtail connector between the oil cooler lines and the engine block. Using the pull wire as a guide, pull the sensor pigtail along the top of the oil cooler lines and around to the rear of the engine. Use the pull wire to pull the pigtail into position. Disconnect the pull wire from the sensor pigtail. Connect the sensor pigtail to the harness connector. Thoroughly clean the mating surfaces of the CKP sensor and the engine block. Install the CKP sensor with a new O-ring seal into the engine block. Install the fastening bolt (1) for the CKP sensor. Check the harness for proper routing. Make sure that the wiring cannot come in contact with the exhaust manifold. Tighten the oil cooler lines at the engine block. Install the oil filter. Lower the vehicle. Recheck the engine oil level.

check if it is the blower motor running on after the power is cut

Engine Oil Pressure Gauge Switch Lower right front of the engine Blue/green an Blue/yellow wires going to it ! Blue

fuel pressure on injected cars must be 40-50 lbs

most likely an electrical problem.

200. 00 per wheel

you have to remove the dash panel to replace the bulb, if the bulb is good you could have a bad computer

Your heater core is running off of the coolant for your engine. It i essentially a "mini radiator" inside the car. When the temperature drops that low, it takes longer for the coolant to get up to temperature. If it never actually gets hot, its time for a new thermostat. For most cars it is a fairly cheap repair, around 20$ for the thermostat, 10$ for coolant and labor, usuall usually 1/2 hour total job, so figure around 80-100$ total if done at a shop.

Sounds like the head-gasket blew and allowed oil into the coolant and coolant into the oil. Unfortunately, it's time for a tear-down and rebuild of the engine.

could be a blown head gasket..

Looks head gasket,you can try head gasket fix,there is new product I sow in auto zone $ 45.00.

You blew a head gasket no way a new radiator will fispx this issue !!!!!!!!

Go under the hood where the horn is and unplug it. Its only a temporary fix.
