On the left when the wheel is turned slowly. Both the less costly Toyota Camry and 4Runner models have buttons to disengage the Vehicle Stability Control (VSC) and the traction control (TRAC) feature. The output voltage should fluctuate up and down similarly to the diagram Specified Condition = Generated intermittently Measure the voltage of the combination meter connector as the wheel is turned slowly. However, this has been a completely different story. I’ve normally been able to pull the engine codes and then fairly quickly diagnose and repair the problem. Shift the lever to the neutral position.ĭ. On my 2003 Toyota 4Runner, I’ve been dealing with a Check Engine Light (codes P0031 & P0051 came up simultaneously), and the VSC TRAC and VSC OFF lights for the past year. Reconnect the combination meter connector.Ī. Measure the voltage between the terminal of the combination meter and the body ground.ĭ. Disconnect the C10 combination meter connector.Ĭ. The vehicle speed sensor is operating normally if the speedometer display is normal.Ī. Drive the vehicle and check if operation of the speedometer in the When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was LEAN or RICH, and other data from the time the malfunction occurred.Ī. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. Read freeze frame data using the intelligent tester or OBD II scan tool. The ECM will turn on the MIL and a DTC will be set. If there is no signal from the vehicle speed sensor with these conditions satisfied, the ECM concludes that the vehicle speed sensor is The ECM assumes that the vehicle is being driven when the transmission counter gear indicates more than 300 rpm and over 30 seconds have passed since the park/neutral position switch was turned OFF. The ECM determines the vehicle speed based on the frequency of these pulse signals. The skid control ECU converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM via the combination meter.
