I have a 2004 Hyundai sonata 2.4L engine with automatic transmission. When a crankshaft sensor is replaced, it is neccessary to have the timing belt and its tensioner replaced also?

Watch the video of the replacement job 2004 Hyundai Sonata Optima V6 2 7 crankshaft position sensor location and...

Make sure all electrical connectors are in fact connected, especially on the transmission side of the engine, under the air boxes and ductiing. Signals from the crankshaft position sensor and camshaft position sensor(s) are what tell the ECM to fire the spark plugs and fire the fuel injectors.

there are 2 pieces to the crankshaft sensor...one is a little round thing that is mounted under the valve cover on the driver side. The other part plugs into this and the cable runs down under the other side of the engine. The sensor is inside the timing belt cover.

i had your problem a month ago and had the little round part replaced and that worked for me.

In the factory manual this code translated to a erratic signal from the Crankshaft Position sensor. I would check the connector to the sensor first and the wiring as well. The sensor is located above the crankshaft front pulley under the timing belt cover.

My online Sonata manual shows these possibilities, but does not identify which applies specifically to 2000 Sonata.
Also, when you talk to the dealership parts counter, you'll need to know whether your 2000 Sonata is (a) 4-cylinder 2.4L MFI DOHC engine, or (b) 6-cylinder 2.5L MFI DOHC engine.
Its easy to tell - just count your spark plug wires.

The CPS for these motors is located in the front of the engine and the the timing belt cover needs to be removed to gain access. If you need further instructions on removal as well as diagrams, email me at [email protected] and I will send those immediately.
