So, the CEL light came on my friend's car and I pulled off the following codes from the handy dandy code reader from the forum....

DM:
4 Air injection system faulty hot film mass air flow sensor with hot wire
9 Intake air temperature sensor, open circuit

Pin8:
3 Intake air temperature sensor

Pin14:
5 Stop lamp switch (S9/1)
14 Closed throttle position contact switch

Looks like the first order of business is to change the MAS on the car. Is this the correct diagnosis? We are also curious about the codes in Pin14. Any ideas?

Cheers,
Clive
