What does exhaust camshaft position Timing Over Advanced mean?
The exhaust camshaft has advanced too much when the ECM has commanded the camshaft to retard to a lower timing level. The oil viscosity is excessive causing the passages to become clogged, causing oil flow to and from the camshaft phasers to be restrictive.
What does intake camshaft position timing do?
The variable valve timing system increases fuel economy and engine performance by regulating when the intake and exhaust valves are opened and closed. The camshaft(s) is(are) adjusted by the ECM through the use of an oil control valve(s) (OCV) also called variable valve timing control solenoid valves.
Can a bad timing belt cause a Kia Rondo to not start?
They are most commonly found on four cylinder engines. Here are some of the most common signs of a bad timing belt on the Kia Rondo: Engine Won’t Start – If your Rondo’s timing chain or belt has fallen off completely, broken, or has jumped a few teeth, it is entirely possible that the engine won’t even start.
What does a tensioner do on a Kia Rondo?
The tensioners job is to keep the right amount of pressure on your Kia Rondo’s timing belt or chain. As the belt/chain stretches through normal operation, it would get loose and fall off or jump. The tensioner keeps this from happening by keeping a consistent amount of force on the belt.
How does the timing of the exhaust camshaft work?
There is no variation in valve timing of the exhaust cam because the exhaust camshaft is driven by the timing belt. The timing of the intake cam is varied by the relative operation the CVVT vane to the housing. The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV (Oil Control Valve).
Can a timing belt be used instead of a chain?
Timing belts are not that common. You’re much more likely to find a timing chain in cars and trucks than belts. Smaller cars, particularly Japanese made ones, can use timing belts instead of a timing chain. They are most commonly found on four cylinder engines.

When do you know to change the timing chain?
A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle and it’s a few hundred dollar repair. A timing chain doesn’t need to be replaced unless there is a problem with it.
Why is my timing chain wearing out on my RX 350?
The timing chain problems are not uncommon, especially in high-mileage vehicles. Similarly to any other moving mechanical components inside any engine, a timing chain is subject to wear. A timing chain is lubricated by the engine oil. Lack of oil changes, low oil level or poor oil quality can cause the timing chain to wear faster.
