Top 20 2001 Buick LeSabre Questions & Answers

Question edited for clarity 'modular' to module'. Question moved to model category It is in the air cleaner box. What do you intend to do with it. Any work with transmission needs diagnosing electronically. A professional grade bi directional scan tool is the answer to this. It can operate the transmission solenoids and verify that they are operating, https://www.google.com/search?q=mobile+auto+electrician+near+me Location https://www.google.com/search?q=2001+buick+lesabre+transmission+control+module+location ..

forget all that ABS lamp stuff (BUT IS GREAT TO WARN) it is telling you the brakes are bad. (WHY IS VAST) 1: ALL FUSES GOOD. 2: OBD2 SCAN THE CAR, AND FOR SURE ABS SCANS TOO. 3:IF ABS SCANS SAY A SENSOR IS DEAD, I MAY BE OR THE WHEEL LOCKS UP. 4: BRAKES ARE BAD, SORRY ABS CAN NOT HIDE BAD BRAKES., EVER. IT CAN ALLOW A TAD WEAK BRAKES AND TUNES FOR THAT. BEST IS FULL SCANS. PCM AND ABS BOTH USING REAL SCAN TOOLS THAT DOES GM. (BOP +CHEBBY) BAD BRAKES OR , BAD AXLE BEARINGS BAD CALIPERS, OR THE SLIDER PINS RUSTED AND JAMMED. BAD PADS BAD CALIPER PISTONS. BAD WHEEL SENSORS. CABLES CUT ABS MODULATOR DEAD AND FULL OF RUST INSIDE,DOOMED. BRAKE FLUID LEAKS ANYWHERE, NOT ALLOWED;. OIL FROM SEALS BAD AND LEAKS TO PADS ROTORS BAD, OR X10 WORSE CRACKED THIS MEANS A FULL BRAKE INSPECTION IS DONE. MASTER CYLINDER DRY OR FULL OF 21 YEAR OLD USELESS FLUID? AND IS FULL OF WATER NOW>? DOT3/4 IS A WATER SPONGE.

Cerainly - only way to know for sure is to to do a battery load test. However, replacing the starter without the correct shims can also cause this problem.

The fastest way to check for the problem is to have a scanner hooked up to the obdii system and see which sensors change when you shift into drive.

Can't do it that way.....have to replace A/C compressor with idler pulley

Malfunction The evaporative control (EVAP) system captures any raw fuel evaporating from the fuel storage system (e.g. the fuel tank, filler neck, and fuel cap). Under precise operating conditions-dictated by engine temperature, speed, and load-the EVAP system stores and purges these captured fuel vapors back into the combustion process. The carbon canister, which stores the raw fuel vapors, utilizes a vent valve that allows fresh air to enter the EVAP system. This displaces the fuel vapor as it's purged into the combustion process. Code P0449 indicates that the evaporative control (EVAP) system vent valve solenoid is malfunctioning. This can be caused by either too little or too much electrical resistance or a mechanical problem with the vent valve itself. P0449 Symptoms

• Check Engine Light will illuminate
• In most cases, there are no adverse conditions noticed by the driver
• In some cases, there may be a noticeable fuel odor caused by the release of fuel vapors

Common Problems That Trigger the P0449 Code

• Missing fuel cap
• Defective Evaporative Vent Valve
• Defective or damaged fuel cap
• Distorted, damaged or cracked Fuel Tank Filler Neck
• Torn or punctured Evaporative system hose(s)
• Defective Fuel Tank Sending Unit gasket or seal
• Split or damaged Carbon Canister
• Defective or damaged fuel tank

Common Misdiagnoses

• Fuel cap
• Evaporative Purge Valve
• Evaporative Vent Valve

Polluting Gases Expelled

• HCs (Hydrocarbons): Unburned droplets of raw fuel that smell, affect breathing, and contribute to smog

Hello, Assuming you did replace with the same type of air-shock, it may seem simple, however ensure the hoses are reconnected and air tight. Spray soapy water on the air lines to check for leaks (you'll need to adjust the load to ensure pump function). Speaking of pump function; check your pump by turning the key to ON. Wait 30 seconds and you should hear the air pump running under the right rear of the car (under the trunk next to the subframe). If you can not hear the pump running, then check all fuses. If fuses are good and pump does not run, then it may be time for a replacement pump. I hope this helps.

Have the engine cradle bushings checked by an alignment shop. Sleeves on these have a track record of rusting away on older cars.

If the pintle is stuck you should replace the valve.

You'll have to splice extra wire onto each conductor and seal both ends of each splice with special 3M tape to keep out moisture. You'll also have to match the wire gauge of each wire. Very tedious job, but doable as long as you take your time and don't take shortcuts.

You need to use the windows more often.To put the window up.start the car,go to the door with the window stuck down,now,as you hit the button on the door to the up position,HIT THE DOOR HARD! The window will go up but it may take a few tries.Push button up just as you hit the door hard.A rubber hammer helps get a good hard hit.

https://s1.postimg.org/1cnkgsihzz/start_1_relay.jpg Click on the link, you can see the start 1 relay, underhood fuse box. You can see the start circuit breaker and pcm fuse. Not only check the circuit breaker and fuse, use a test lite and check voltage at fuse and circuit breaker. The CB is hot all the time, the fuse goes hot with key on. I noticed in the diagram, the start relay has no pin numbers on it, sometimes that means the relay is soldered into the fuse block circuit board, you can't pull it out. You can try to pull it? The ground for control side of relay is grounded by pcm. I didn't see neutral switch mentioned in diagram, that switch is a thought. Just my opinion.

GM makes wire harnesses for multiple models with one harness, so not all connectors are used, if you have digital display......that may be problem .....check all fuses

It could be a bad coolant sensor(new or not) could be the map. Get some electrical parts cleaner and take the map out and clean or replace it. It is a very easy job to do. If your unsure do a search on it and watch a few videos on it.

That's either a salvage yard or the dealer. Explain or show them what your looking for

have battery retested-or ac electrical for parasite drain

Maybe your thermostat is bad, stuck inclosed....this would boil water before the thermostat and not get to the temp control for the fan, also, ckk bottomhose for collapse.Have you ever changed hoses? Ever put in new thermostat?. They do go bad.

put the accelerator pedal down at least twice ? While cranking the engine ? key on ? what ? Your vehicle has electronic fuel injection ,not a carburator . Pushing the gas pedal doesn't do anything The only thing if pushing the gas pedal to the foor an holding it there will put it into clear flood mode , shutting off the fuel injectors .

Dirty fuel injectors.Remove and clean or take to dealer,cost about a 100 bucks,then it will fly again.
