ECU Fault Codes

[Brunty]

I've just done the engine fault code test as desribed by Zentac HERE as I know I've got AYC issues.

I had a refurbished pump installed by Roger Rally at the weekend, which appeared to resolve the problem initially, but after 5minutes driving the dreaded AYC light came on. DISCUSSED HERE.

Just wondered if anyone can shed any light on the other fault codes I got as listed below. The battery was disconnected on Saturday during the AYC pump installation so these 'faults' are likely to be current. TIA.

Neutral and Engine Light - continuous rapid flashing

ABS
12 - Air Flow Sensor
13 - Intake Air Temperature Sensor
14 - Throttle Position Sensor
15 - ISC Motor Position Sensor
21 - Engine Coolant Temperature Sensor

AYC
82 - AYC Pump

Really want to know how serious the sensor faults are and whether I need to worry about anything.
