    TL 3.2 V6 - car began running very rough yesterday and shortly thereafter the check engine light came on, followed by the TCS indicator coming on. All looks well under the hood with proper fluid levels, but there is a hint of burning rubber. Checked the belt and it seems fine. This happened while RVing in Selma, Al and not knowing where to take it we opted to tow it back to Nashville. The car starts fine but idles very rough and the check engine indicator comes on immediately, followed shortly by the TCS indicator.

2000 Acura TL changed the fuel pump car runs good but now the TCS light and check engine light are on.


the TCS light will come on any time the check engine light comes on. Pull codes from the engines computer to see why the check engine light is on. Post the codes in the comments below and I'll do my best to assist you further.

The TCS light came on and the car started jerking especially at stops. The light would go off for a while after restarting the car but the same problems would happen and the light would eventually come...


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.

Tcs light, check engine light flashing and constant shaking..


Use an OBDII scanner, some auto parts stores will do this for you free of charge.
Codes P0300 through P0306 indicate mis-fire and you may also get codes reflecting Cat damage from running that way.
I know of one TL from this series (2000 3.2 TL) which had a warranty REPLACEMENT OF TRANSMISSION!!! free of charge and this very problem was solved. I still do not know why they were related. Talk to Acura customer relations about this.

you may have a faulty crankshaft position sensor this is what controls the firing of the plugs. you may also have corrosion on the plug for the coil pack causing multiple misfires

TCS and Engine Light are ''ON''. Engine misses badly.


A part is most likely malfunctioning causing for the TCS to turn off. You'll have to get a diagnostic check to determine what part is failing. What ever that part may be is causing for the misfire.

Check engine light + TCS = braking vibrations


You need to get to a repair shop and have them read the diagnostic codes (the computer port is in the center console under the change holder/lighter). With that amount of mileage, it is very likely the code will show that the oxygen sensors and/or catalytic converters need replacement. If that is the case you will also need a tuneup (plug, wires, etc). I had this done a year ago at 160,000 miles. It is a pricey repair but I get 29mpg at highway speeds and it runs nicely on regular (less power but no pinging).
