Re: need frequency valve help

You need to check all of the inputs to the lambda module.The temp 
switch, the lambda relay, the oxygen sensor,etc. In my case it was a 
bad lambda relay, the module has a low failure rate. It could even be 
as simple as a fuse or as we saw in Richmond one car had a bad 
frequency valve.
