John brings up a great point,... When measuring high resistance values, or voltages with very low current (such as the Lambda sensor) it's always a good idea to use a decent DMM (Digital Multi Meter) or DVM. The internal impedance of a DMM is very high, and won't load down the circuit you're reading. Some analog meters have a low impedance and may give you an inaccurate reading by changing the circuit you are reading.
