Re: Way to test TCS safety valve? Posted by SWEDECAR [Email] (#112) [Profile/Gallery] (more from SWEDECAR) on Sat, 8 Mar 2003 22:33:50 In Reply to: Way to test TCS safety valve?, bstan, Sat, 8 Mar 2003 19:45:40 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The best and only way is to drive the car until really hot, or place the valve in a hot enviroment. Next you measure the resitance over the two pins when the valve is still hot. It should be around 30 Ohm.
If it is above 45-50 Ohm, it start to go bad. If the reading is around the hundreds or more, the valve is bad.
The coil inside the valve goes bad with rising heat. When a bad valve is cold, the reading is back to around 30 Ohm.
