2015 Mazda CX-5 Sport 2.5, 150k miles
Looking for where the knock sensor is on a 2015 Mazda CX-5 with a 2.5l engine. Any help is appreciated!
Yep, the intake manifold needs to be removed in order to gain access to the sensor. I recommend examining the connector/wiring and testing with a multimeter before hanging on the new part and reinstalling the manifold.... Based off other cars I suspect it's under the intake but would prefer to know before tearing into it.
How bad on deposit the intake valves were? Any pictures to share? Is there much oil in your intake? At 120K miles, it’s time to change engine coolant too, especially you’d removed overflow coolant tank.I cleaned everything before I put it back together. The car has 120k on it. I ended up doing spark plugs as well
Did you tear one or did they come off intact?It wasn't terrible but it was needed. Unfortunately I didn't think to take any pictures of it. I was more concerned with the knock sensor location. The Throttle body had some carbon build up as well. Slight oil in the intake. My biggest surprise was how hard it was to get intake and throttle body gaskets. Mazda wanted 100+ for them, rockauto was $7. But it was a 2 week wait for them. In retrospect I could have reused the old but didn't want to risk tearing one without having it on hand.
I assume you got an OEM knock sensor, how much is it? Have you eliminated the P0327 code after the new knock sensor?It wasn't terrible but it was needed.

It's $30 per intake gasket. There are 4 gaskets on your intake.Maybe the price was for the intake manifold itself, that's too much for only a gasket. I paid about $30 for a genuine mazda valve cover gasket.
