Exhaust Gas Temperature (EGT)
If an EGT sender is suspected to be faulty then the best method to check the actual sender is to swap
the leads that go into the SkyDat data box. When the engine is operated if the opposite display then
shows the same reading as before this will confirm a faulty sender.
To change the wires use the following procedure
1. Obtain a flathead screwdriver with an approx 2mm head.
2. Note the colour of the wires for each position. – Write these down, and preferably mark the left
and right hand side EGT wires to make it easy to replace them.
3. Use the small screwdriver to push into the hole above each wire connection, do not force. This
releases the wire and allows each to be removed individually.

4. Remove both sets of wires and place the “Faulty” EGT wires into the side which has been
receiving a signal.
5. Now if there is still no signal then the EGT sender needs to be replaced.
6. A further check may be made of the resistance of the sender. Use a multimeter to measure the
resistance of the sender. An open circuit clearly shows that the thermocouple circuit is broken
and will need to be replaced. Typical values for the resistance of wire are:
RHS Sender – Approximately 1.8 Ohms.
LHS Sender – Approximately 3 Ohms.
7. Order the EGT sender, note that there is a left and right hand side as they are different lengths.
8. Release the wires from the sender that is to be replaced, note the wire routing which is used.
Undo the EGT.
9. Replace the EGT, make sure that the copper washer is in place (no sealant is required). The
approximate torque for the EGT is 22Nm. Take care not to cross thread.
