Hello all. New member here. I have had this CX-5 GT since ~2021 (75k miles). Literally no issues, just regular oil changes and tires. Now at 168k miles. While driving Friday night - accelerating around 20 mph, a really bad pinging/rattle occurred for about 2-3 seconds. I actually thought a cv axle broke based on the sound. I can't remember if I turned the engine off or it stalled, but it would not restart. Tried reconnecting the MAF and coils + checked fuses. No results
Went out and bought an OBD2 reader. Codes were
- P0365 - Camshaft position sensor B circuit (Bank 1)
- P061B - Internal control module torque calculation performance
- P061D - Internal control module engine air mass performance
- P0102 - Mass or volume air flow circuit low input - may have been from messing with the MAF after the fact??
- P0113 - Intake air temperature sensor 1 circuit high input
I replaced one camshaft sensor with an aftermarket sensor. Tried switching that new sensor with the other location. I can hear the fuel pump prime under the seats. Pulled all of the spark plugs to inspect. Oil in one of the cylinders from a valve cover leak. Plugs were old and worn but otherwise unremarkable. Tested spark with the worst condition plug and I'm getting 1 spark on crank, then no more (almost like ECU is cutting spark).
At this point I gave up and had the car towed home. I bought a compression tester. all cylinders getting 110-120 psi. Low, but shouldn't cause no start. I tried starting fluid in the intake so see if it was a fuel issue. Tried clearing the codes and this time caught just 2 codes
- P0365 cam sensor again
- P0335 Crankshaft position sensor A circuit
Today: ran to autozone to get the only crank sensor in stock. No improvement. At this point worried about timing maybe being off?? Pulled the valve cover to inspect. In doing so, I unfortunately broke the plastic on the VVT solenoid so I will replace that. Timing at TDC looks perfect with a tight chain and no visible wear on the guides, cams look good. There were a couple of scratches near the solenoid. I will post a picture if I can.
Unfortunately, I'm at the end of my expertise. I'm going to order and try OEM camshaft & crank sensors plus a new solenoid, at which point I have no more tricks.
Would a bad VVT solenoid cause a crank no start with cam & crank codes? Is something bigger going on? Has anyone ever experienced this?
Edit: I should also note that I replaced the battery yesterday as well, just in case
