DIY repairs: Valve cover gasket(1/02/12),Plenum gasket(1/02/12), Crank Sensor(1/20/12),Rotors and Pads(1/21/12), Oil Sump Gasket(1/22/12),
Oil Pump, Timing Chain kit, Head Gaskets, New Water Pump, Thermostat, New hoses, New 8mm Wires, Bosch +4 plugs, New Fluids all the way around, mikes 60k mile service complete, Exhaust gaskets (2/1/12 - 2/29/12).
The evap system uses a small electric pump. The system tests the pump against and detects leaks as small as .02 inch by low pump current, and blockage by high current. In your case the pump current has exceed 40 milliamps, and this is one of the codes that can be cleared, then take four driving cycles to re-appear. Probably a bad DMTL pump (Diagnostic Module Tank Leakage). See attached.
I tried to upload the JPEG instead of the PDF, but the smallest I could get the file and still see it was 200kb. I think it says it needs to be like 19kb. So I'm sorry. Anyway

Thanks for the advice. I tried to find a replacment on AB but couldn't locate it. Any idea of the Part Number?
Also, I noticed the hose connected to the Purge valve was in bad shape. 100_1803.pdf
I replaced it to see if that would help. My purge valve has been clicking like crazy at times. Is that normal or could that be related to the P1453?
I also took a look at the EVAP air filter and blew it out a little with the air hose. 100_1804.pdf
While getting the air filter I noticed this cut wire near the air filter canister.
I think this is/was the speed sensor wire. 100_1805.pdf
However it looks like the sensor runs to this extra long roll of wire and is fed through the firewall. I didn't see any connection. Just one long wire all the way to the hub, and no way to disconnect it if I needed to change it ever. 100_1810.pdf
