@StarBear .
here is what i have on the Temp Sensor II inbuilt into the AFM on the 1.8 L Jetronic. i could be wrong but i don't think there is any effective way to test the air temp sensor in the AFM on our adam/eve in the garden of eden L Jetronic system. that sensor is not wired in separately. but maybe there is an expert here who knows. - in relation to the problem you are having with hot days and ultra high humidity causing the idle to drop to barely running - i'm not sure the symptom fits a faulty Temp Sensor II in the AFM. others here might know better. I would not have thought a faulty sensor would cause that dramatic a result. Temp Sensor 1 (CHT) - yes. but Temp Sensor II no. i am sure @Van B will pipe in with a more learned view. I would have thought Temp Sensor 2 fault would make the car run rich. I think that is how it would work. but again i am probably wrong. i'd have to think about it. most trouble shooting literature i can dig up says failure mode causes car to run richer generally. increased fuel consumption. |

Don’t want to get off topic but isn’t the temp sensor I only on the ‘75/‘76 models (hence the 7 pin connector)?

The TempII sensor is integrated into the 74 AFM, not separate with own pin. See Haynes page 177, wiring diagram 3. Trick will be to check/confirm if mine has an issue. |
