How a CVT transmission works

CVT transmission operation A CVT transmission has some of the same components as a traditional automatic transmission. For example it has: • Torque converter • Pump • Valve Body • Clutch pack • Sun Gear But it also has: Two variable sheaves (pulleys) Pushbelt (can be steel or rubber with impregnated steel elements CVT pushbelt Many early model CVTs used a rubber belt with impregnated steel elements. However most late model CVT transmissions use a steel ring with steel elements. The ring can have multiple wraps to make it stronger. … Read More

Kia P2096 Post Catalyst Fuel Trim System too Lean (Bank 1) Diagnose and fix Kia P2096 Post Catalyst Fuel Trim System too Lean (Bank 1) Kia constantly monitors the upstream and downstream oxygen sensors and constantly changes fuel trims to compensate for rich/lean readings. To properly diagnose a Kia P2096, read the live data on a scan tool for the upstream and downstream oxygen sensors. The upstream sensors should rapidly switch from low to high voltage while the downstream sensor should stay at around 0.6-0.7-volts. If your readings show rapid … Read More

Common Causes of Alternator Failure

Most Common Causes of Alternator Failure Electrical causes of alternator failure 1) Attempting to fully recharge a dead battery using the vehicle’s alternator. The alternator is designed to replenish the battery from the last start and to supply extra power during engine operation. It is NOT designed to output maximum current and voltage for long periods, especially at low engine RPMs found at idle. This causes the rotor, stator and diodes to overheat and fail. Prolonged Maximum Charging Output will cause premature alternator failure. Never operate your alternator for more … Read More

Battery Conductance Testing

Battery Conductance Testing — What is it? Most DIYers think that a battery’s voltage is the only indication of its condition. Wrong. Battery voltage only tells you the battery’s State of Charge (SOC), it does not tell you anything about the battery’s State of Health (SOH). To determine battery SOH, you need to conduct either a load test, an internal resistance test or a battery conductance test. What is a battery load test? Using a carbon pile, the battery is loaded to half of its rating cold cranking amp ratings. … Read More
