Nissan Micra Throttle body (Bosch type) year 2000 onwards

Very common problem with the Nissan Micra year 2000 onwards, causes power loss and sometimes stalling or revving problems. Nissan moved on to using the bosch type throttle body for the later Micra’s in an effort to get rid of the problems they had with the older style throttle body used on the earlier K11 Micra, but it seems they have made the problem worse as the Bosch versions seems to be failing more often than the old version did. We can supply these throttle bodies from stock with Lifetime warranty*.

Emissions Failures -

High CO & low lamna reading. common causes of rich running faults are the lamna sensor or the ECU (engine control unit) both of these parts are relatively simple to check, to check the sensor strip back the insulation on the signal wire from the lamna sensor, this wire is usually black. Then hold the bare wire between your finger and thumb then touch your other hand on to the battery positive the internal resistance of your body will give 1volt at your finger tips which is what the sensor would give out when the engine runs rich, if the emissions come down then you have a faulty lamna sensor or wiring but if the emissions remain the same then the ECU is a possible fault.
