2000 buick century problems

DTC P0131 HO2S Circuit Low Voltage Sensor 1 The PCM supplies a bias voltage of about 450 mV between the HO2S signal and low circuits. When measured with a 10 megaohm DMM, this may display as low as 350 mV. The oxygen sensor varies the voltage within a range of about 1000 mV when the exhaust is rich, down through about 100 mV when exhaust is lean. The PCM constantly monitors the HO2S signal during closed loop operation and compensates for a rich or lean condition by decreasing or increasing injector pulse width as necessary. If the HO2S 1 voltage remains excessively low for an extended period of time, DTC P0131 will be set. Do you have a advanced scan tool to check O2 sensor data ? This video is on a honda but your's works the same Honda Civic P0131 02 Sensor Diagnosis

Cooling transmision lines

Make sure that you use thee correct tools when removing the hose. Important to keep in mind that these lines seize up so you may need to heat the fittings. When installing new line, good idea to use a little anti-seize and then top off transmission fluid with vehicle running and it has reached operating temperature.

Dash lights either work or not if the system is fused. With one light not working it suggests the problem is the lamp(bulb). I am sorry to say it has to be dash insert out to access behind where the lamps are located. Only competent people should do this for you. Only when the lamp is checked can you determine if thats the problem or if the fault is else where.

On a2000buick century odometer not working

You would need to take it to the dealer or someother qualified repair shop that has the diagnostic tool to check for DTC'S - diagnostic trouble codes in the instrument cluster . DTC B0570 Season Odometer Malfunction The instrument cluster receives a vehicle speed input from the vehicle speed sensor (VSS) over the Class 2 line. This signal is used in order to drive the speedometer and the odometer of the instrument cluster. The instrument cluster will compare the VSS data with a 16-point look-up table in order to determine needle deflection. A smooth filter is used in order to secure a continuous response. The season odometer displays the total accumulated kilometers (miles) of the vehicle. This value is permanently stored in the Electronically Erasable Programmable Read Only Memory (EEPROM) of the instrument cluster. The trip odometer displays the accumulated kilometers (miles) to the tenths of a kilometer (mile) since the last reset. This value is stored in Keep Alive Memory (KAM) of the instrument cluster. Test Description The numbers below refer to the step numbers on the diagnostic table. Always perform the Instrument Cluster Diagnostic System Check before attempting to diagnose this DTC. This diagnostic procedure requires using a scan tool. This repair procedure requires instrument cluster replacement. Step Action Value(s) Yes No 1 Did you perform the Instrument Cluster Diagnostic System Check? -- YES - Go to Step 2 NO - Go to Diagnostic System Check - Instrument Cluster 2 Using a scan tool, clear the instrument cluster DTC and retest for DTC B0570. Does DTC B0570 reset? -- Go to Step 3 Go to Powertrain On Board Diagnostic (OBD) System Check in Engine Controls - 3.1L or Powertrain On Board Diagnostic (OBD) System Check in Engine Controls - 3.8L 3 Replace the instrument cluster. Refer to Instrument Cluster Replacement . Is the repair complete? -- System OK Go to Diagnostic System Check - Instrument Cluster © 2017 General Motors Corporation. All rights reserved.

I have a 2000 Buick century 3.1 I smell gas when it starts but can't locate where its coming from I changed the fuel filter hoses and checked the fuel pump it smells like its coming from the hood

You may have a fuel injector that is leaking tiny amounts of fuel at the connection to the fuel supply pipe that sits over the fuel injectors, check there and replace any seeping "O" ring seals that you find. There should be stains from any fuel leaking, look carefully.

Code po507 came up on my 2000 Buick century. Service engine light flashes when I accelerate and vehicle runs rough. Any help diagnosis on this?

That has to do with your idle air control valve (IAC). It is controlled by the pm and more diagnostic tests are needed to narrow down exactly where the problem lies. Check all wiring and connection to IAC and pcm 1st. I’m happy to assist further over the phone at https://www.6ya.com/expert/kim_3202917d7c587455

Can i get some steps and tips for cleaning the throttle body on a buick century 3.1 2000

There are spray cleaners for that purpose available at auto parts stores. Spray it all over the inside if the throttle body without the engine running. Let it sit for a while to loosen the dirt. Spray again and then start the engine. Spray more to clean past the throttle plate.
