Todays GM vehicles use many sensor, switches, solenoids, and other electrical components to control or monitor every aspect of the
engine.
From controlling the fuel and ignition systems, to monitoring the emissions.
A problem in any of these systems, or subsystems, can cause the check engine light to come on.
The first step in any diagnosis of the check engine light is to get the computer (PCM or ECM) scanned for codes. Any time this warning
comes on, a code is stored in the computer memory along with many data parameters that were present at the time of the fault.

Answer: Your scanner would need to be able to read the Remote Control Door Lock
Receiver (RCDLR).
If one of the wheel sensors were bad, it should just show 1 tire pressure as a "--". You
could try a re-learn procedure with or without a scanner.
If there is an overall system problem, it says "service system"
There is a bulletin for changing the receiver module, antenna, and remotes that may
apply.
There is an article on our site with more detail.

| 4-2-11 what is code P0440 for a 1999 Astro van mean? |
Comments
| P0440 is a general fault in the Evaporative Emission System. You may have a leak, a sensor or valve problem. Or maybe the gas cap is loose or the Astro van was running when filling with gas. |

| 11-5-11 I have a 2001 Chevy Monte Carlo SS. My dash lights went out and I had a ground repaired, not replaced. Then I had a new BCM installed. Did not fix the problem. When he repaired the wire it fixed it for about 3 or 4 mos. In sure it must be the same wire, I just need to know where it is. |
| You will have to be more specific. Every module has many different grounds. Try calling the shop that did the work and ask them. |
| 11-17-11 P0440 check the wire harness on the canister; |
| 11-17-11 I had same problem with dash lights. I replaced the headlight/dimmer switch. Perfect fix. |
