Hello Albert,
yes, heater resistance is normal (both sensors).
maybe I wrote badly.
you must
1. turn off the ignition
2. remove "connector 1" from the computer.
3. measure the
resistance between "pin
30" of "connector 1" and the body(
ground). Should be 2-5 ohms.
4. Measure the
current between "pin
30" of "connector 1" and the battery (
positive terminal). Current must be 2..5A
Important - as I see it, your multimeter can only measure
2 amps, so you have to take another device, usually they can measure current up to 10 amps, but you need to connect the red probe to another hole in the device. It's hard for me to explain this to you because of the language barrier, but there are a lot of people here who know it all professionally, for example,
Thomas. Perhaps they will see this topic and prompt.
for an example, look at the description for a cheap Chinese multimeter. Here you can see how to measure the current (where to connect the probes and which mode to choose)
