Car running rough or getting a check engine light for the VVT system? This A-Premium 2-piece solenoid set might be the fix for your 2012-2015 Scion iQ with the 1.3L engine. It includes both the intake and exhaust side Variable Valve Timing (VVT) solenoids, so you replace them as a pair for best results. They're direct replacements for OEM part numbers 153300Y050, 153300Y060, 918-097, and 918-098. These are electromagnetic solenoids with a 2-pin blade connector, 12V operation, and a plastic housing - built to meet or exceed OEM specs. Comes with a one-year warranty for some buying confidence. If your iQ is hesitating, losing power, or having timing-related issues, these solenoids are a common culprit. Good for DIYers who are comfortable working under the hood. Always double-check fitment for your specific model and year!
