Code P1000 Ford Description

The P1000 Ford diagnostic trouble code indicates that the On Board Diagnostic (OBD) system readiness test has not been completed. This means that certain emissions-related systems or components have not been fully tested by the vehicle's computer. The OBD system conducts self-tests to ensure that the vehicle is meeting emissions standards set by the Environmental Protection Agency (EPA). When the readiness monitors are not complete, it can prevent the vehicle from passing an emissions test and may also hinder the detection of other potential issues with the vehicle. This code does not necessarily indicate a specific problem with the vehicle but rather indicates that the system has not completed its self-checks.

  • Unfortunately we can't cover all the Ford models, but I check the factory service manual and the information above is the same. The P1000 just means that computer diagnosis cycle didn't finish. Just clear the code and you are good to go.

  • My 2008 Ford F-150 will not start code is P 1000 what can be causing this problem

  • No, I haven't seen the P1000 code causing a no start problem. More than likely the problem is something else e.g. Fuel pump, battery/alternator, starter, etc. Unfortunately there are many thing that can cause the a no start problem.
