What is the ohms range for injectors in a 2001 7.3L powerstroke?

2.9 ohms is nominal. To check the resistance remove the IDM module and probe the connector with an ohm meter. Do not pierce the wires. The injectors are activated with around 100 volt pulses. Cut or pierced wires will leak current and cause injector drop out, or IDM failure.

How do you know that the sensor is bad?
Find out the ohms range it must be within and do an ohms test.
The 1994 Dodge engine 5.2 used 19 lb 14.6 ohm injectors and the 1998 same engine uses 19 lb but 12.5 ohms and all else is the same what would happen if you used them in your 1994 engine?
That's an excelent question. I have asked on a forum the similar question, and the replys i received were one of two 1) there are two types of injectors one is high reading ohms and the other is low reading ohms. as long as you stay within either the high or low range (high 14.8 to 12.0) then everything will be just fine, and therefore you can use it. 2)if the ohms are not a match (14.6 plus or minus 0.4 ohms) then you can not use them and it will fry your computer. So which is correct? I'll have to watch to see what other people say.

What is the voltage of fuel injector for 96 olds cutlass ciera?
U really dont need to know the volts to your injectors just the resistance they put out use a multimeter to test the ohms of the injectors to make shure they are functioning proplerly

Whet does 4-8 ohms mean?
this is range of 4 ohms resistance in an electrical device. Ohms is a measure of resistance in electrical qualities. Circuits and devices are rated , or measured for there resistance in ohms to meet a designed electrical need. Is this related to a speaker?
