Removal

Sensor of a detonation of system of injection of Simtec fuel

1 – sensor;

2 – bolt


PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Disconnect electric sockets from the sensor of temperature of the air coming to the engine and the measuring instrument of a stream of warm air.
3. Remove hoses of ventilation of a case.
4. Remove hoses of supply of cooling liquid from the branch pipe coming to the engine of air, the tape measuring instrument of mass of a stream of warm air together with an air branch pipe from the top part of the air filter and the case of a throttle.
5. Using a screw-driver edge, release brackets of fastening of nozzles of the first and fourth cylinders in strips of the socket and at the same time lift strips. From a reverse side of strips there are six connections, four of which are intended for fuel nozzles.
6. Disconnect electric wires of the sensor of a detonation from a socket strip.
7. Tie a piece of a wire 1 m long to the electric socket of the sensor of a detonation.
8. Remove the detonation sensor from the block of cylinders of the engine (see the drawing).
9. Untie an additional wire from the electric socket of the sensor of a detonation.

Installation

Installation is made in the sequence, the return to removal taking into account the next moments...

PERFORMANCE ORDER
1. Clear the interfaced surfaces of the sensor of a detonation and the block of cylinders of the engine. For fastening of the sensor of a detonation use only standard bolts and washers.
2. Being careful, install the detonation sensor on the block of cylinders and fix by a bolt, having tightened it the required moment.
3. Arrange a detonation sensor electrical wiring between ledges on an inlet collector. Untie an additional wire from the electric socket.
4. Insert the electric socket of the sensor of a detonation into a strip of sockets.
5. Arrange spring brackets of nozzles so that they did not interfere with gearing of strips of sockets. Check that between a strip of sockets and a nozzle there was a reliable contact.
6. Record strips of connecting sockets before the heard click.
7. Check a condition of hoses and reliability of fastening by their collars.
