Code 41 - EST Circuit (Electronic Spark Timing) or CMP Sensor, No distributor Reference pulses to the PCM at specified engine Vacuum, A malfunctioning ignition module can very easily cause this code to set. If the EST circuit is either open or grounded it may very well cause the same problem. Hope this helps.

You are geeting a PO128 error message on 2001 Chevy Astro?
I have the same van and had the same problem. The error code PO128 is an error code letting you know you need to specifically replace the Coolant Temperature Sensor. The Sensor is about $14.00- $15.00. Just a little work, not bad. I did it and actually helped my gas mileage also. I would recommend Advanced Auto Parts.
