More than likely it is a fuse. Or the remote needs to be program. I would start by testing the fuses because sometimes they look good but they are not. If all the fuses are in good condition, take the car a dealer and have the remote reprogrammed.

Need to replace the liftgate switch, where can I get instructions to do that?


How do you know it need's a switch ?
Rear Hatch/Gate Description and Operation
The lift gate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the lift gate actuator through the body control module (BCM). The BCM will pulse the lift gate actuator when a release input is received through the key fob, or the instrument panel switch. Did you test voltages ? Check for BCM DTC'S - diagnostic trouble codes ?
Circuit/System Description
The lift gate switch is an input to the body control module (BCM). The BCM supplies battery voltage to the signal circuit and when the lift gate switch is activated the signal circuit voltage goes low. The BCM controls the lift gate release actuator assembly through the LIFTGATE relay. When the lift gate switch signal is activated, the BCM enables the LIFTGATE relay by applying battery voltage to the lift gate relay circuit and the relay is energized when the BCM grounds the LIFTGATE relay control circuit. When the relay is energized battery voltage is supplied to the lift gate release actuator assembly through the lift gate release actuator control circuit.

00 Camry 2.2 egr problem po 401 low flow new egr valve new solenoid new transducer new map clean passages. I don't know what else to do


Here is an overview for the code as it relates to Toyota cars.
I would go back and make sure the tubes and pipes are clear.
In most cases, the passage is plugged up, or the sensor does not "see" the flow.

Possible causes
- EGR passage clogged
- Faulty EGR Vacuum Modulator Valve
- Faulty EGR Valve
- Faulty EGR solenoid valve
- EGR solenoid valve harness is open or shorted
- EGR solenoid valve circuit poor electrical connection
- Dead (Weak) battery
- Faulty EGR temperature sensor and circuit
- Exhaust gas leaks

Idles rough in reverse


either your EGR valve, but then you would also receive a traction control/stabilitrack light, or you could be due for spark plug and ignition wire/spark plug wire replacement(tune up)
I have a 2008 torrent that was doing the same thing but I also had my EGR Valve causing the stabilitrack/traction control light to come on. I thoroughly cleaned my EGR tube, ports in engine and EGR Valve as well as the air intake(all with carb cleaner) then reassembled and changed my spark plugs and ignition/spark plug wires. with NGK parts. solved my problem so I hope this will help you as well

Erg code 405 how do test it


Potential causes of a P0405 code include:
Short to ground in EGR signal or Reference circuits
Short to voltage in EGR ground or signal circuits
Bad EGR valve
Bad PCM wiring issues due to chafing or loose terminals


Possible Solutions:
If you have access to a scan tool you can command the EGR valve on. If it responds and the feedback indicates the valve is moving properly then the problem may be intermittent. Sometimes in cold weather, moisture can freeze in the valve causing it to stick. After the vehicle warms up the problem may disappear. Carbon or other debris can lodge in a valve causing it to stick also

If the EGR valve doesn't respond to your commands with the scan tool, disconnect the EGR harness connector. Turn the key to on position, engine off (KOEO). Using a voltmeter, check for 5 volts on the reference wire to the EGR valve. If there is no 5 volts, is there any voltage at all? If there is 12 volts, then repair short to voltage in the 5 volt reference circuit. If there is no voltage connect a test light to battery voltage and probe the 5 volt reference wire. If the test light illuminates, the 5 volt reference circuit is shorted to ground. Repair as necessary. If the test light doesn't illuminate check for an open in the 5 volt reference circuit. Repair as necessary

If there is no apparent problem and there is no 5 volt reference, PCM may be at fault, however other codes will likely be present. If 5 volts are present on the reference circuit, jumper the 5 volts to the EGR signal circuit. Now the EGR position on the scan tool should read 100 percent. If it doesn't connect test light to battery voltage and probe the EGR signal circuit. If it illuminates, then the signal circuit is shorted to ground. Repair as necessary. If the light doesn't illuminate, check for an open on the EGR signal circuit. Repair as necessary.

If, after jumpering the 5 volt reference circuit to the EGR signal circuit the scan tool EGR position reads 100 percent, then check for poor terminal tension at the EGR valve connector. If the wiring is okay, replace the EGR valve.

Hope this helps.

DTC P0405 - Exhaust Gas Recirculation Sensor A Circuit Low

There are different designs of EGR (Exhaust Gas Recirculation) systems, but they all operate in a similar way. The EGR valve is a PCM (Powertrain Control Module) controlled valve that allows measured amounts of exhaust gasses to pass back into the cylinders to be burned with the air/fuel mixture. Since exhaust gas is an inert gas that displaces oxygen, injecting it back into the cylinder can lower combustion temperatures which helps to improve NOx (oxides of nitrogen) emissions. EGR isn't needed on cold startup or at idle. EGR is commanded on under certain conditions like startup or at idle. EGR is commanded on under certain conditions like partial throttle or decel depending on engine temperature and load, etc. Exhaust gasses are supplied to the EGR valve from an exhaust pipe or the EGR valve may be mounted directly in the exhaust manifold. When needed, the valve is commanded "on" allowing the gasses to pass into the cylinders. Some systems divert exhaust gasses directly into the cylinders while others simply inject it into the intake manifold where it is then pulled into the cylinders. while others simply inject it into the intake manifold where it is then pulled into the cylinders.

Some EGR systems are quite simple while others are a little more complicated. Electrically controlled EGR valves are directly controlled by the PCM. A wiring harness plugs into the valve itself and is commanded by the PCM as it sees the need. These can be 4 or 5 wire. Usually 1 or 2 grounds 12 volt ignition feed, a 5 volt reference circuit, and a feedback circuit. Other systems are vacuum controlled. These are quite simple. The PCM controls a vacuum solenoid which when activated, allows vacuum to travel to the EGR valve and open it. There should also be an electrical connector on this type of EGR valve for the feedback circuit. The EGR system feedback circuit allows the PCM to see if the EGR valve pintle is actually moving as it should. If the feedback circuit detects that the voltage is unusually low, or it's position is lower than it's commanded to be, P0405 may set.


Symptoms of a P0405 DTC may include:
MIL (Malfunction Indicator Lamp) illumination


Potential causes of a P0405 code include:
Short to ground in EGR signal or Reference circuits
Short to voltage in EGR ground or signal circuits
Bad EGR valve
Bad PCM wiring issues due to chafing or loose terminals

How do you repair codes PO141 and PO136 2000 Ford E-350 with a 5.4 engine


Causes A code P0401 most likely means one or more of the following has happened:
  • The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced, this is the common cause
  • There is a blockage in the EGR (tube), most likely carbon buildup
  • The EGR valve is faulty
  • The EGR valve may not be opening due to a lack of vaccuum
Possible Solutions In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
  • Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
  • Clean out the EGR valve and/or tubing to remove deposits
  • Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
  • Replace the DPFE sensor (with a good quality / OEM one)
  • Replace the EGR valve

Symptoms There may be no visible symptoms to the driver. Poor fuel mileage, possible misfire, depending on O2 sensor position when sticking.
Causes A code P0136 may mean that one or more of the following has happened:
  • Faulty O2 sensor leak in exhaust close to O2 sensor, faulty O2 sensor is the common cause.
  • Short to voltage on O2 signal circuit
  • Open in circuit resistance caused by corrosion in connector
Possible Solutions
  • Replace the second oxygen sensor on bank 1
  • Repair open or short in signal circuit
  • Clean corrosion from connector
