Review Of 2002 Honda Accord Check Engine Light Is On 2023. The check engine light is also on and we pulled the code and it said that the tcs will not engage. Web if the oxygen sensor is faulty or has failed in accord, it can cause the ecm to receive inaccurate readings, which can result in the check engine light being triggered.
In some vehicles, the light comes in two colors: Three of them told me i need to replace the catalytic converter and the other three told me i need to change the oxygen sensor. It’s a warning light that alerts the driver about any type of engine problems.
