Operation CHARM: Car repair manuals for everyone.
Manuals through 2025 now available!

Our trusted friends have launched a new website named LEMON, which has newer manuals. It also contains all the CHARM manuals.

LEMON is the spiritual successor to CHARM, I recommend you try it!

Solenoid Resistance Chart

Temperature Resistance
-40° F (-40° C) 3.4 Ohms*
68° F (20° C) 4.5 Ohms*
122° F (50° C) 5.0 Ohms*
176° F (80° C) 5.5 Ohms*
230° F (110° C) 6.0 Ohms*

* These values may vary slightly. When a solenoid is suspected to be causing a problem, an accurate way of checking resistance is to compare the resistance value of the other solenoids. Values should be within one ohm of each other.
