sensors on 2.5 v6

i have a grand vitara 2.5 v6. its been great up until this week. it has stood unused for the last 6weeks following a full service. when i started it again the engine management light came on, so i took it to the local garage, who put the diagnostic tester on it and said that it shown up different faults each time. they say that the only way to sort it out is to replace the 4 sensors. anybody got any ideas, as the alternative seems costly. only 29000 miles done so dont want to change it.help. brian uk

Take it to the dealer, they don't know what they are doing. And what 4 sensors is he talking about, because there are a lot more than 4. You have 4 oxygen sensor, crank sensor, cam sensor, throttle position sensor, mass air flow sensor, and more.
