The check engine light came on in my 2003 Honda CR-V and the dealer told me it was the Throttle Sensor and quoted a charge of $700.00 to replace. A friend said the charge was mostly labor as the part was under $100.00 and also said it is fairly easy to replace. Is this true and how do I obtain a part that is comparable to the Honda part used by my dealer?

Your throttle Sensor is riveted to your Throttle body. Your friend is right in most case, it usually involves two screws and a connector with a little adjustment and your off. Your SUV is a little different, granted you can still do the repair yourself if you like but finding the part will be a little tricky. You can try salvage yards if you want to take the chance but you will need to by the whole throttle body and replace it whole. Might be a little cheaper the salvage way if you have some one to replace it on the side and not a going through a shop.
