Under the dash.

P0335 is a code for a faulty crank angle sensor. When this sensor starts going bad, usually the car will not start till it cools down, may cause rough running or no start at all. P0727 is a communication error between the engine control module and the transmission control module. Check for any bad connections between both modules.

Starter Replacement Removal Procedure Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information. alt="Object Number: 217186 Size: SH">

you dont unscrew the cover,you pull the plug wire to access the plug and then use an extension with your socket

Did you recently have a loss of power to the car? change the battery? if so, you need to reset your system. My husband and I just figured this out this weekend. His sunroof hasn't worked in two years and it turns out you have to reset all the power options in the car. Google 2000 cadillac catera %calibrate ETC% loss of power, you'll find the step by step instructions for recalibrating the car's computer and resetting the power options

computer will relearn at it's own pace while driving. no input needed from the driver.

there are two temp sendens or sensors on this car . one operates the gauge the other reports only to the computer. one is in the thermostat housing the other is in the manifold

calipers are not releasing fully. many times they are adjusted out too far when someone attempts a brake job

remove plug and check for oil or fouling. cable should resist1300 ohms. coil could be bad

perhaps antitheft feature is engaged. check for flashing security lite. exit car lock with the remote then reenter car with the remote and insert the key in the ignition turn key to crank position and observe the security light. it should not be flashing

the passive antitheft feature is engaged. lock the car from outside with the remote open with the remote and insert key in ignition and turn to crank position and observe the security lite it should not be flashing

you have one crank sensor and 2 cam position sensors

Hi, it may be that the light on tail may be bad, but usually is the break sensor that goes mounted on the break pedal, it cost about 25 US in Autozone, its important to replace it , since this may affect the information that is being sent to computer about the car speed and how to make the shift (transmission) .. By replacing this you may see that the break lights will work again. Its something that may take about 20 min to a mechanic.

have the codes checked at autozone for free. they will let you know what is wrong

The Catera has a history of stalling/cutoff issues. Many are solved with the replacement of the crankshaft position sensor. It does give the symptoms you describe. I would try that first as it is fairly cheap and easy to replace. If the problem persists after that, you've at least removed one potential possibility. This is the description of the crank sensor from AUTOZONE (cost $44.99 USD)

• The crankshaft position sensor identifies position of the crankshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM)
• When not replaced, vehicle may experience no start, hard start, intermittent engine shut down, misfire, engine cut out, excessive fuel consumption, CEL illumination and/or failed emission test
• Proper alignment, positioning and spacing for faster, easier installation
• Designed to meet or exceed OE specifications in form, fit and function

I know with ignition coils you remove one at a time while engine on and hear for difference

timing issue. a car backfires when fuel is not burnt in the combustion chamber, and end up in the exhaust system. your car could very well just need a tune up.
