CHR check engine light VANOS issue
Summary of the thread
A 2021 Toyota CHR with 74,602 km exhibited an intermittent check engine light and increased fuel consumption, potentially due to a faulty inlet VANOS mechanism. Possible causes included a malfunctioning camshaft solenoid valve or power supply issues. The solution involved replacing the camshaft solenoid valve, which resolved the check engine light issue and normalized fuel consumption.

Engine performance seems slightly diminished, especially at lower RPMs. No unusual noises, though. Regular servicing, yes, always on schedule. Was it definitely the VANOS for you? Anything specific I should tell the workshop to check?

Yeah, it was the VANOS. I didn't dive too deep myself; took it straight to the workshop. They replaced the faulty solenoid valve. I'd suggest you do the same. Might save you a lot of headache.

I took it to a local mechanic who was also sure it was the VANOS. They replaced the camshaft solenoid valve, and the check engine light is now off, and fuel consumption is back to normal. Total repair cost was 250€.

I had a similar issue with my CHR: check engine light, increased fuel consumption. Did you notice any change in engine performance or unusual noises? Could be VANOS failure. Has the car been regularly serviced?
