From VDO tech sheets for testing senders: ( download data sheets from links I posted above)

Sender Testing:

Senders can be tested with an OHM meter that measures from 10 to 2,000 OHMs. Connect the positive lead from the tester to the sender terminal and the negative lead to a good ground. The following readings will occur if the sender is operating properly:

Temperature Sender: Room Temp (Sender Dependent) 300 – 1000 Ohms (•)

Pressure Sender: Engine off (Sender Dependent) 10 Ohms (•), 240 Ohms (•)
