An idle fluctuation may be noted, the Check Engine Light may or may not illuminate. Replacing the throttle position sensor and updating the powertrain control module (PCM) software will commonly correct this concern.

Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct. Also, make sure the computer that controls the transmission has the most up-to-date adaptive programming information. When servicing these transmissions be sure to use fluid approved by Hyundai.

Premature timing belt failure may result in serious engine damage. When replacing a broken timing belt, it is important to inspect and possibly replace the crankshaft position sensor; it is often damaged when the timing belt breaks.

Engine stalling or failure to start may indicate crankshaft angle sensor failure; Hyundai issued a recall (03V030000).

If the Check Engine Light illuminates, indicating a problem with the front oxygen sensor, but the sensor tests okay, reprogramming the engine's control computer should fix the problem. Then, the Check Engine Light will no longer falsely illuminate and the acceleration, particularly from a stopped position, will be smoother.

A faulty engine control module (ECM) ground circuit may cause various issues including stalling, loss of air conditioning operation, and illumination of the Check Engine Light. Our technicians tell us that adding another ground wire to the ECM wire harness can often correct this issue.
