california smog test at 218,000 miles
ive owned this MS 4x4 XLS 3.0 since new. In Kalifornia we test every 2 years as I recall. I had my recent test yesterday and passed all emissions,but since the tech found a light on my instrument panel he had to fail the test. The fail is automatic if a "check engine or service check" amber light is displayed.So, he ran the codes and came up with a P1400 which refers to the Manifold pressure Differential sensor. BTW for those of you that are interested for whatever reason,the cost to this point is $45 for the smog test and $40 for pulling the code. replacement of the sensor will be $345.
Im suprised that after 218K & 14 years no other smog related part or emissions have failed. Im curious,has anyone ,that may have a little OCD for this thing , kept track of any patterns or sequences in the eventual and progressive breakdown of the smog equipment? 2. what is the purpose of this sensor that failed? |
Manifold Differential Pressure sensor should be about $100. Order the part and replace it yourself = save $200 for other things. It is usually located on the top of the manifold and has an electrical connector and 2 screws to bolt it down. Very easy replacement.
