I have a honda civic type r (2002) the engine management light came on so I took it to the garage. The diagnostic test showed cam sensors fault. I had these changed which cost me £300 and the engine managment light is still on. The garage are now telling me it is the crankshaft, the two belts are loose and need replacing. It is apparently an engine out job and will be close to £1000. Is what the garage saying completely accurate?

Its best to change cam and crack sensors at the same time, but as for removing engine to change belts thats a no there is a plate in the wheel arch that needs removing to gain access. removing the wheel and you will see the plate that needs removing. belt change is not hard to do. if the cam sensor has failed and replaced and still a fault then its not this at all that is the problem. you can get a false code, and resetting it and running engine to see if it comes up again. also if the garage is using the right equipment it will be able to diagnose a run test this will tell you the full state of the problem so you don't waste money replacing every single part. a failed Maf sensor on some models can make a cam sensor fail as its linked, and that usually just needs a clean with MAF cleaner, this people change the air filter and forget about the sensor. the muck ats on the air filter can get thought to the sensor and give a false reading. also when a part is replaced the ecu needs to be reset or it will say engine faults any were up 60 starts of the engine. so i would have this done. hope this helps. plus if belts lose you would know while running the engine it will squil or make strange sounds. i would recommend another garage if you are going to this one. use a recommended garage, or a garage specialised to you vehicle. changing parts as they think will cost you more money in the long run. good luck with your repair.
