1 ABS light Illumination. The vehicle dashboard has multiple warning lights and symbols. These warning lights and symbols indicate different problems. The ABS light illumination is one of the most common symptoms of a bad ABS wheel speed sensor. The ABS light is the same as the Check Engine Light except for the ABS system.
Youll notice one or more of the following symptoms: A rough idle upon starting the engine (that is, when the engine is cold) and sometimes at a stop light or while looking for a spot in a parking lot (that is, at low engine speeds in a warmed-up engine). Stalling when the engine idles. Increase in fuel consumption.Falsereadings. One way to know your oil temperature sensor is failing is if you get false readings due to the electrical signal output by the temperature sensor. These are indicated by the temperature gauge going from cool to hot in one minute. It takes a couple of minutes for the oil to heat up, so the temperature sensor should reflect that.
