SOURCE: 1997 buick lesabre, engine light stays on

The are many things that can cause your "check engine" light to stay on. One possibility is that although you have fixed the trouble code for your crankshaft position sensor, the code has not been erased from the computer's memory. Another possibility is that you have another issue going on that is causing a new trouble code to come up. You're going to need to have your car hooked up to a ODB-2 engine code reader to see what the issue is. These code readers are available for purchase at any auto parts store. In addition, many of your local auto parts stores will check trouble codes as a free service to customer. If not, many parts retailers offer the option to rent one of these code readers. Which ever way you decide to go, run a full engine/emissions trouble code check. If the only code that comes up is the code that came up previous to fixing your positioning sensor, then all you need to do is erase the trouble code from the computer's memory. (Most code readers have the option to erase trouble codes, but if you're going to rent or buy one, I would suggest that you check to make sure that the code reader that you're getting is capable of erasing trouble codes as some code readers only indicate the codes and will not remove them from your computer's memory.) If your trouble code scan reveals other codes, then you'll have to fix and erase them as they arise.

FYI- In my experience, I've noticed that 95% of the time that a check engine light/trouble code arises that it is usually an emissions problem (oxygen sensors, mass air-flow units, MAP sensors, etc.). However, General Motors products are notorious for getting trouble codes for having loose battery/ground connections and for having worn-out fuel caps. With any GM vehicle, I always check these two things first to try to save me from having to look further than I need to.

Hope this helps! I'm sure once you've scanned your cars computer and erased any existing trouble codes, that you'll stop being annoyed by your check engine light, as I know how bothersome it can be. Have a great day!

SOURCE: Rear license plate lights burned out and can't

If i remember correctly the entire rear light assembly must be remove in order to access these bulbs. This is true if the license plate is on the trunk. If this is the case then there are nuts on the inside of the trunk that must be removed.

SOURCE: 1997 Buick Lesabre Water Pump problem

THE POWER STEERING PUMP PULLEY --- ARRGGH...Not a problem. The power steering pump is held by two bolts. Use a socket and remove the top bolt and loosen the bottom bolt. Be careful not to completely remove the bottom bolt. The PS pump will loosen up enough so that you can push it towards the firewall and you will JUST have enough room to remove the waterpump bolts. Its tight but it will squeeze out.

This is a fairly common problem, Gm has actually issued a service bulletin regarding this repair. The problem probably originates from one of your wheel speed sensors that is mounted inside one of your front wheel bearings. To be sure, you need to have the car scanned to find out which one and then you have to replace the whole bearing assembly because the sensor is integral to the bearing. The bearing is not hard to do but you will need some professional tools if you want to do it yourself. At a shop it should cost between 3 and 400 dollars complete.

My only thought right now is a dirty mass air flow sensor. Beyond that it would require a scan tool on the transmission to detect if pressures are correct.

Location of crank sensor on 1997 lesabre


The crank sensor should be on the passenger side of the engine. It probably won't be visible without first removing the power steering reservoir, and possibly other items on that side of the engine. It is located down below near the waterpump pulley.

Replace dimmer switch


The headlamps ( high an low ) are controlled by the LCM lamp control module .
Headlamp Dimmer Switch
Under the left side of the IP, on the base of the steering column

Headlights Circuit Description (Buick)
Battery positive voltage (B+) is supplied at all times to the lamp control module (LCM) through the LH underhood fuse block LCM/HDLP circuit breaker via CKT 242 (RED). When the headlamp switch is placed in the ON position, the headlamp switch input to the LCM is grounded via CKT 103 (WHT). The LCM then supplies battery positive voltage (B+) via CKT 12 (TAN) to the following components:
• Left low beam headlamp
• Right low beam headlamp
When the headlamp dimmer switch is placed in the HIGH position, the LCM removes battery positive voltage (B+) from the low beam headlamps. The LCM supplies battery positive voltage (B+) via CKT 11 (LT GRN) to the following components:
• Left high beam headlamp
• Right high beam headlamp
The LCM provides battery positive voltage (B+) to the appropriate headlamps under the following conditions:
• The ignition switch is in the RUN position.
• The ambient light sensor indicates darkness.
The lamp control module (LCM) monitors the ambient light conditions through the ambient light sensor. The ambient light sensor is a variable resistor whose resistance changes as the surrounding ambient light level changes. As the ambient light decreases, the resistance of the ambient light sensor increases. The LCM measures the resistance across the ambient light sensor and determines whether it is day or night.

The cold ambient sensor is located at the lower part of the ac condenser in the front. You need to get the fuel pressure checked and fuel pressure regulator also.

1997 Buick Lesabre 3800 engine. Mass Air Flow. Cleaned honey comb screen in air body by MAF but after 150 miles with air on, code 102 turns on check engine light.


Good Evening. You did the right thing cleaning the honeycomb, you should try cleaning the elements on it. It is a very good first step to try that, however if it is kicking on a check engine light feel lucky because the MAF sensor can do things that will also not kick on a check engine light. my words of having been there before would be to replace the sensor. Hope this helps, and if you have any more questions please feel free to ask.

Need Mass Air Flow Sensor for my 1997 Buick LeSabre Custom


not unless you take it to autozone and have them put the scanner on it and clear the code which caused the light to come on. also they can tell you what the original issue was.

unfortunately it sounds like you just started to replace parts and honestly you could have already repaired the issue
