GENERAL INFORMATION

The temperature EGR sensor is mounted near the recirculation valve. The sensor traces change of temperature of exhaust gases when passing via the recirculation valve.

Information on temperature comes to the control unit which precisely regulates time of inclusion / switching off of the valve, providing increase of efficiency of purification of exhaust gases. At violation of operation of the temperature EGR sensor in memory the code 71 registers.

Check

PERFORMANCE ORDER
1. Disconnect from the conducting socket.
2. Measure sensor resistance at various temperatures. Standard values of resistance at various temperature are specified in subsection 6.1.

Replacement

PERFORMANCE ORDER
1. Disconnect the socket of conducting and Rozhkov a key turn out the sensor from an inlet collector.
2. Installation is carried out upside-down.
