Checking the pulse output would have verified the problem, but we cannot find what the voltage should be.

After we replaced both assys with the correct OEM parts it would not start.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

We had a 996 come in with a bad clutch & flywheel. After we replaced both assys with the correct OEM parts it would not start. Among the multiple fault codes found was "reference sensor" code. We replaced the sensor & cleared the codes. Veh started w a bit of effort & idled well, however it would not pull over 3,000 RPM. When the fault codes were checked, the "reference sensor" fault was present again and the motor stayed flat. The sensor position is fixed, it cannot be adjusted or moved. We installed another new sensor, cleared the codes and the same fault came back. After scratching our heads on this for a while, we pulled the flywheel and found the trigger ring out of round but no sign of damage or being bent. The original box also showed no sign of external damage. Apparently the out of spec trigger ring caused the failure to rev over 3k. Has anyone else experienced such a problem? Checking the pulse output would have verified the problem, but we cannot find what the voltage should be. Len at Autosportengineering dot com

POST 2Original post

Maybe electrical parts disconnected with out the battery disconnected? It wouldn't be the first time a manufacturer or warehouse persons boxed up a wrong part.

POST 3 / ORIGINAL POSTEROriginal post

Once the flywheel was replaced and codes cleared, performance returned to normal. Eng revved to 7k as it should, w no fault codes. My question is what are the pulse values? I should be able to read them on a scope. Any recommendations as to how to do this? Len
