Measured all inputs, outputs, all OK. The "handshaking" between TCM and ECM seems to work perfectly. However the "load" signal makes no sense to me. There is no test for this signal. It is ECU connector #39 to TCM #B16. Using my Digital meter I can measure a frequency of 12HZ at idle, this increases in a linear manner with RPM. Voltage is about 380 mv. These 2 measurements I think are normal. Duty cycle at idle is about 17% but it jumps to 100% as soon the throttle is opened even the smallest amount. This does not seem right. Now here is the interesting part. Vacume is only about 13" at idle, this seems very low, should it not be higher? Does this indicate a vacume leak? Have checked all lines at the "tree". Could I have a manifold gasket leak? Is this affecting the load signal, causing the lumpy idle, and causing engine fault code 232? -- David Hunter Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.
