Most likely a sensor, short E1 and Te1 on diagnostic link to retrieve codes, check engine light will flash.

Ok, you will need to pay close attention to the flashes. There will be a series of them and look something like this.............

flash (short pause) flash flash = 12

flash flash (short pause a second or 2) flash flash flash = 23

And so on

Now a long pause (4 - 5 seconds) between flashes indicated new code.

You may need to repeat the proceedure a few times just to make sure you are counting correctly.

Engine Codes....

12 Engine RPM Signal.
13 Engine RPM Signal.
14 Ignition Signal.
16 ECT Control Signal.
21 Oxygen Sensor (OS) Signal.
22 Water Temperature Sensor (THW) Signal.
24 Intake Air Temperature Sensor (THA) Signal.
25 Air/Fuel ratio lean.
26 Air/Fuel ratio rich.
27 Sub-oxygen sensor signal.
28 Main Oxygen Sensor (OS) Signal.
31 Air Flow Meter Signal.
32 Air Flow Meter Signal.
41 Throttle Position Sensor (TPS).
42 Vehicle Speed Sensor (VSS) Signal.
43 Starter Circuit Signal.
51 Switch Condition Signal.
52 Knock Control Signal.
71 EGR system malfunction.
