A code P0402 most likely means one or more things has happened. The DPFE (differential pressure) sensor is faulty and needs to be replaced, there is a blockage in the EGR (most likely carbon buildup) or the EGR valve may not be opening due to a lack of vaccuum.

Stop in at autozone or similar parts store & get free code scan, then see which way to go from there. Cheaper & faster than guessing.

You may have to dig deeper for a vacuum leak. It's possibly the intake manifold gasket. Try spraying some starting fluid around the intake manifold. Also try disconnecting the brake booster and plugging that hose, the diaphram in the booster could be ruptured, causing a vacuum leak. Check the PCV valve and hose too.

SOURCE: 2002 Mazda Tribute rear liftgate lock replacement

I'm not sure where' the screws are but basically You need to remove the panel on the rear door, then once the panel (interior trim) has been removed you should see a lock mechanism which will be screwed/bolted in place. Easier and cheaper then buying a brand new lock mechanism (unless you want to buy brand new) is going to a wreckers and finding your car model and get it that way (yes it's used but it'll probably save you tons of money vs the dealership) Best Regards.

How to fix a dtc p0507?


A vacuum leak Leaking air intake after the throttle body EGR valve leaking vacuum A faulty positive crankcase ventilation (PCV) valve Damaged/failed/dirty throttle body Failed EVAP system Failed IAC (idle air controller) or faulty IAC circuit

Hy is there a code p0507? and how do i fix?


This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set. A P0507 DTC trouble code may be caused by one or more of the following: A vacuum leak Leaking air intake after the throttle body EGR valve leaking vacuum A faulty positive crankcase ventilation (PCV) valve Damaged/failed/dirty throttle body Failed EVAP system Failed IAC (idle air controller) or faulty IAC circuit. This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect the intake air system for air or vacuum leaks and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns. If you have an advanced scan tool that can interact with the car, command the idle higher and lower to see if the engine responds appropriately. Also check the PCV valve to see if it's blocked and needs to be replaced. Check the IAC (idle air controller) if equipped, verify it's operation. If available, try swapping in a new throttle body to see if that fixes the problem. On Nissan Altimas and possibly other vehicles the problem may be fixed by having the dealer perform an idle air relearn procedure, or other relearn procedure

P0507 KIA Idle Air Control IAC System RPM Higher Than Expected

CHECK ENGINE LIGHT IS ON


This Code is about the RPM not matching the idle settings. A Vacuum leak is tricking the engine into making adjustments based on a lean O2 reading. Correspondingly the O2 sensors are demanding more fuel to eliminate the lean readings. Then the engine realizes the amount of air going by the MAF is not matching the IAC settings(Because the air leak is increasing rpm) and blames the IAC which is a Code P1506.

With the engine running, use an old spray bottle and fill it with water. Spray the seams, vacuum lines and solenoids until you notice a change in RPM. Lastly, spray the EGR pod if the diaphragm is torn it will leak vacuum.

Wherever you find the leak, fix it, then clear the computer and drive it.

Won't idle


It used to be that this was nearly always bad engine timing, but nowadays you suspect first the IAC valve being stuck or clogged, and then possible vacuum leaks in the inlet manifolding. Others have found a clogged PCV valve to be the cause.
