Diagnosis and Part Selection Advice:

How did you know this part needed replacement? Why did you choose a certain brand/part number?


Took car to Canadian Tire in Kirkland, Quebec - Mechanic told me what needed replacement and that it was no longer available from the dealer GM Canada Note: the indication that the Map Sensor was defective is the CHECK ENGINE lamp lit on the dash.

Repair / Installation tips:

Special tools needed? Have to remove other parts to reach this one? Any left-hand threads, sharp edges, messy fluids or other pitfalls to avoid? Mechanic had no problem replaceing the old unit with the new one. It corrected the problem. Warning, the new one went defective after I shampooed the engine, water may be damaging it. So, bought another and will find another way to clean the engine.
