p105b ???? What scan tool did you use to pull this code ?DTC P0105 is the correct DTC. Where do you people learn this stuff .I have 7-8 g/s vacuum??? What the heck is this ?? The only thing you'd see Grams a second on would be a mass air flow sensor , not the map sensor . Vacuum to the map sensor would be manifold vacuum . 18 - 22 at idle. MAP Sensor Eng 1, 2, 3 Volts 0.94-2.0 volts Varies with altitude Dirty throttle bore ,plate ,EGR valve sticking open a little . The PCM calculates a predicted value for the MAP sensor based on throttle position (TP) and engine speed. The PCM then compares the predicted value to the actual MAP sensor signal. If the PCM detects that the MAP sensor signal is not within the predicted range, DTC P0105 sets. 034 Engine Misfire Vacuum Leak Test

Controlled by a liftgate control module . A bad sensor input to the module is probably the cause . If you know nothing of automotive electronic's (control module's ) your best bet mite be to take your vehicle to a qualified repair shop.

Flashing check engine light is due to a severe misfire in 1 or more of the cylinders. If not diagnosed and repaired quick you will ruin your catalytic converter. There are a few things what can cause this from timing to faulty coils to faulty injectors to electrical ... to name a few.

Testing the system an not replacing parts is the way to find the problem . Without knowing how ,using a factory diagnostic flow chart to go by would be best for a rookie . System Description The control module tests the evaporative emission (EVAP) system for a large leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running are met, the control module commands the EVAP canister purge valve OPEN and the EVAP vent valve CLOSED . This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the control module commands the EVAP canister purge valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. If the system is unable to achieve the calibrated vacuum level, or the vacuum level decreases too rapidly, this DTC sets. Conditions For Setting the DTC The EVAP system is not able to achieve or maintain vacuum during the diagnostic test. Diagnostic Aids • To help locate intermittent leaks, use the J 41413-200 Evaporative Emissions System Tester (EEST) to introduce smoke into the EVAP system. Move all EVAP components while observing smoke with the J 41413-SPT High Intensity White Light. • A temporary blockage in the EVAP purge solenoid, purge pipe or EVAP canister could cause an intermittent condition. Inspect and repair any restriction in the EVAP system. • To improve the visibility of the smoke exiting the EVAP system, observe the suspected leak area from different angles with theJ 41413-SPT . • Reviewing the Failure Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition. • For intermittent conditions refer to Intermittent Conditions . Inspect the EVAP system for the following conditions: • A loose, missing, or damaged service port schrader valve • A loose, incorrect, missing, or damaged fuel fill cap • A damaged EVAP purge solenoid Raise the vehicle on a hoist. Refer to Lifting and Jacking the Vehicle in General Information. Inspect the EVAP system for the following conditions: • Any disconnected, improperly routed, kinked, or damaged EVAP pipes and hoses • A damaged EVAP vent solenoid or EVAP canister Did you find and correct the condition? Smoke testing the evap system to find the leak would be your best bet .

Muy facil. Usar translator para esto, mi espanol, no esta bueno. You probably disconnected the battery prior to this problem happening. Take out fuses #10 and #28 under the hood. Clean your throttle body with a sensor safe spray, it's best to remove the throttle body to do this. 4 bolts, OK to use the gasket again. Use a spray like Seafoam, works good, use a soft bristle brush like a toothbrush to clean.

Try asking at auto parts store , sounds like a linkage problem

Manually shift the truck into park at the transmission. Then make repairs to shift cable. Lock the truck and then use the key to unlock the door and start the truck.

disconnect the arm coming from the motor to the track of the sunroof, slide it closed

Your best bet , take it to a qualified repair shop . There are no magical fixes for problems like this . The windows and locks are controlled by a control module ( electronics ) . Without testing using a scan tool an proper diagnostic procedures ,looking at wiring diagrams an testing electrical circuits with a DVOM -digital volt ohm meter . I see this all the time at the dealer i work for , shorted wiring , BCM - body control modules , door modules , class 2 serial data network . You have no idea of the complexity of all this . Do you know what DTC'S are ? Diagnostic trouble codes ! DTC B1017 or B3970 (Passenger Door Module (PDM)) The Passenger Door Module (PDM), upon receipt of a Class 2 message or a direct lock or unlock switch input will supply battery positive voltage to the internal door lock and unlock relays control circuits. DTC B1023 The switch that failed and generated this diagnostic trouble code (DTC) is part of the DDM or the PDM. When a switch is activated, the DDM/PDM then either actuates the appropriate component or sends a message over the serial data link to the appropriate module to actuate the appropriate component. DTC B1550 DTC B1720 DTC B1721 DTC B1723 DTC B1724 DTC B3808 DTC B3809 DTC B3819 DTC B3820 DTC B3821 DTC B3822 DTC B3823 DTC B3824 Could be any number of thing's ,so if you don't want to replace a bunch of parts that are not needed ,do yourself a favor an take it an have it diagnosed at a qualified repair shop.

Hello Deborah, Place a spark tester on your coil lead to test for spark. If you have fuel pressure, reasonable compression and a spark your engine should at least try to start. Why did you replace the coil packs in the first place? and did your vehicle run before the swap?

These are known for their bad hazard switches causing problems with the turn signals

try replacing or cleaning the injectors when misfiring moves around it is seldom the coils , plugs and any thing else connected to spark but dirty fuel, low fuel pressure and dirty injectors or injector control use a quality injector cleaner for a few tankfills

no gears indicates that the torque converter clutch servo/solenoid s faulty probably a disconnected wire from your working with the others

It must be something else making your check engine light come on.

Check the tranny where cable attaches, you should feel clicks when moving shifter if not your not shifting tranny.

Hello TMAF... TRIED most of that TOO... Finally my codes... said the OXYGEN SENSORS were complaining... OBD... DTC (on-board-diagnostic... DIAGNOSTIC TROUBLE CODES) So... of course I changed the... OXYGEN SENSORS. The "NEW" OXYGEN SENSORS complained just as well... I have subsequently learned the "SENSORS" are just doing their job... In my case reporting on a collapsed catalytic converter. (muffler is actually a MORE common blockage). A little hunting around... like Auto-Zone ... Napa auto... Pep-boys... O'Reilly Auto Parts... even MIDAS might yield FREE READINGs... (check around). Just remember to wear your best SALES RESISTANCE... and look up you prices on ROCKAUTO... before you go... Hope this helps. (Unless FREE, I'd make a SPECIAL note (YELP) on that "shop"... THEY ARE CLOWNS...!! (in my humble opinion... not MECHANICS)).

sounds like a blown transmission, reverse bands are burnt.
