Had the EML read tonight, code P1622 MAP cooling sensor. The guy shown us it's the one on the thermostat housing. I've just removed the connector to get the sensor out & the top of it just came off leaving the rest of it in the housing. The thermostat housing is plastic. Does the thermostat come with the new housing, also does the new housing come complete with the new sensor?

Is this normal?

Thanks:thumbsup

its not a plug for a sensor its a plug for a heating element within the stat it melts the wax and opens the stat controlled by the ECU ie: MAP cooling..


stat complete is around 40 quid with housing...
