MGF Rover 1.8 MEMS 1.9 1995 - Can MAP sensor in ECU be replaced - Fixed #

Posted by Phil Dunmore on August 23, 2012, 3:02 pm

Year of Manufacture *: 1995
Engine Size and Code *: 1.8
( Optional ) ECU Type: MEMS 1.9
( Optional ) Scanner Used: KTS

Fairly certain we have a faulty MAP sensor in ECU. Anyone know if they can be replaced?

not just oil contamination in map sensor.

Don't think so John. No sign of oil in trap or pipes.
It works correctly until the ECU warms up then goes erratic giving high readings(less vac) driving system very rich. Checked actual vac stable with mityvac tee'd into pipe. As it cools readings stabilise again.

Correct part is no longer available, hence question about repair.

Open up the ECU and re solder any dry joints.

Pried the lid off, circuit board well coated in semi transparent gunge, no obvious problem. Hammered lid back on and sent to ATP. Came back super clean. Refitted, all ok.
Thanks to all for the suggestions.
