Thanks for the info, I've carried out all theses checks on the TPS. Rotating the TPS records nothing on the speedo 0mph. with the TPS Reconnected and the engine running rotating the TPS does cause some fluctuations in the engine tone but not a great deal. If a TPS goes defective will this cause the Rev counter to stop working?
