I have a Suzuki Sx4 2008, the engine light is on and the problem code is P-0500, I just replaced the left-front bearing 2 days ago, and also the ABS light is on, could tell me what the problem is and how I...


P0500 is a problem with the vehicle speed sensor. The ABS light on is also caused by this P0500 code.

Get the vehicle speed sensor checked, see if the wiring is causing the problem (frayed). If there is no problem with wiring, try replacing the vehicle speed sensor.

My 2008 Saturn Vue ABS and TCS lights suddenly came on. Is there a sensor connected to this problem?


Yes. Wheel speed sensor. I have an 08 Vue. Same problem happens every year. They say its a corroded wheel speed sensor. Happens every January, always on the left rear. Think they have a design flaw, but GM doesn't appear to agree with me.

The TCS stands for Traction Control System, I believe. The TCS is controlled by inputs from the wheel speed sensors. If you have a bad sensor, then a new hub may be required to repair it.

The check engine light may be a sepawrate problem. Have the codes scanned for both the Anti lock braking sytem, TCS, and the check engine light.

Sometimes it will require a separate scanner for the TCS/ABS vs. the Check Engine light.

Good luck on this diagnosis and repair.

Hi


To start with check the Speed Sensor on the front and rear. Usually the issue is with the rear speed sensor which can be replaced easily and will cost you around $25-$40.
There is a sensor at the top of the rear differential for the ABS system. When the ABS sensor on the diff goes bad the Speedo no longer will work, the odometer stops recording mileage and both brake and ABS light comes on. You also loose O/D or "Lock-up" in the torque converter. The sensor is inexpensive and can be changed in about 30 mins.
Replace rear differential speed sensor as follows:
a) Remove parking brake cable bracket (1/2" socket)
b) Remove speed sensor bolt (9/16" deep socket)
c) Remove metal speed sensor cover
d) Remove speed sensor from rear differential housing (use channel lock pliers, twist gently back and forth while applying upward pressure. Once the speed sensor has a small gap between it and the rear differential housing, insert a flat-blade screwdriver and gently apply upward pressure while gently twisting speed sensor back and forth.
e) Disconnect speed sensor from speed sensor cable
f) Lubricate new sensor with WD-40, insert into rear differential housing. It will NOT go in all the way by hand, so do NOT force it nor hit it with anything made out of metal.
g) Replace metal speed sensor cover
h) Insert speed sensor bolt and tighten LIGHTLY until a small amount of pressure is felt. Tap speed sensor with rubber hammer until it pops into housing. Finish tightening of speed sensor bolt.
i) Replace brake cable bracket, replace 1/2" nut and tighten
j) Disconnect positive battery cable for 2 minutes, reconnect positive battery cable

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

ABS light, light come on goes off and comes back at 5-10mph


have had simmilar problemn with my 1992 licoln towncar do have a solution however will cost hundreds you have a ABS speed sensor out as u kno the problem is you cannot only replace one because they are wire through the axels you have to replace both meaning either both front or both rear in your case if front driversside is faulty you will need to replace both unhooking will only cause light to permantely stay on one suggestion that may help atleast to get an inspection would be to dissconnect sensors to that paticular wheel shut off engine and restart when light is off dissconnect batter for 5 mins then reconnect tghis will reset computer inside possibly giving you enough time to get an inspection befoere computer resets and abs comes back on however it is not guarented to work depends on severit y of damaged sensor and how quickly you module can reset note that this is a temo fix abd sensor will not prevent any stopping or cause danger to braking system it will infact stil engage possibly not on that wheel but that is the problem with an abs as apposed to just a standard anti lock braking system more sensor to break and cost hundreds

TCS/SLIP & Check Engine Light Warning


TCS is Traction Control System,and all TCS's are controlled though the Anti Lock Braking (ABS) system.Here's how it works:Each wheel,or in some cases,only the drive wheels have a speed sensor mounted near the hub or axle,and sends a speed signal to the PCM (Powertrain Control Module).The PCM monitors wheel speed continuously,and if it sees a speed out of the ordinary,say for example the right rear tire is spinning and traveling at a much higher speed than the left rear,the PCM will pulse the brakes through the ABS system on the right rear to slow down the right rear so that the left and right wheel speeds match up,this is how the traction control works.So,if you have a TCS problem,the PCM will see this and set a Dignostic Trouble Code (DTC).You need to pull the DTC's out of the system with a scan tool,diagnose and repair the DTC's.It could likely be something as simple as a malfunctioning wheel speed sensor,but you won't know until the codes are pulled out,as this will point in the general direction.Good luck.
