P0405 EGR code on Chrysler Products

Rick — Sat, 04 Feb 2012 15:44:27 +0000

Many Chrysler products use EGR transducer to detect the actual movement of the EGR valve. The computer commands the EGR valve to open a certain amount. Then, the transducer measures exactly how far the valve actually opened. This transducer sensor has a very high failure rate. In most cases a P0405 EGR Sensor A Circuit Low is caused by a bad sensor. There are two way to go about this fix. You can buy a new EGR valve with sensor, or you can buy just the transducer. Buying just the transducer will save you money. Unfortunately, not many parts stores carry them. But you can give it a shot. First go here to find the transducer part number. Then call the parts store to see if they stock it. If not, go here to buy the entire EGR valve.

Dodge Caliber SRT4 check engine light

Rick — Mon, 19 Apr 2010 22:24:25 +0000

Owners of 2008 Dodge Caliber SRT 4 models complain of a check engine light that translates in to a specific cylinder misfire code. If the 2.4L turbocharged vehicle was built before 4/18/08, the problem is likely due to a software glitch. Re-flashing the PCM with the most current software is the only way to fix the problem.

Chrysler Heater A/C Control Calibration Routine

Rick — Fri, 29 Jan 2010 19:33:41 +0000

The blend and mode doors on late model Chrysler vehicles are driven by DC servo motors. If the motors get out of synchronization, the control head doesn’t know where they are. That can result in cold air when you command heat and vice versa. It can also screw up where the air blows.

Here’s how to perform a calibration routine on Caravan, Voyager, and Town and Country. It works on many other Chrysler products as well.

1. Turn Ignition switch to ON

2) Press both the POWER and RECIRCULATE buttons at the SAME time and HOLD for at least 5 seconds.

3) The POWER and RECIRCULATION lights will flash

4) Calibration should take about about 2 minutes to complete if you have heater control and about 20-seconds if you have Automatic Temp Control system.

5) If lights continue to flash AFTER 3 minutes (manual system) or 20-seconds (Auto system), the control unit has detected a failure. You need a scan tool to pull the trouble codes (Thanks Chrysler). If there’s a trouble code stored, the lights will CONTINUE to flash until the unit completes a successful calibration OR until the vehicle has driven 8 miles.

If your Chrysler vehicle doesn’t have this setup, contact me and I’ll look up the procedure for your particular vehicle.

Headlights flicker on vehicle with daytime running lights

Rick — Sun, 06 Dec 2009 18:02:10 +0000

Every manufacturer has their share of problems with daytime running lights. Basically the system senses that the vehicle is running and the headlight switch is off. Programmed conclusion? Must be daylight, otherwise the driver would turn on the headlights. Other systems have light sensors. The Chrysler Daytime Running Light system gets screwed up by corrosion in the intelligent power module. Some GM vehicles fail due to a cracked Daytime Running Light resistor (computer provides power to the headlights, but runs it through a resistor to cut down on the headlamp brightness). Still another GM system runs the headlight commands through Daytime Running Lamp Module located behind the left side of the instrument panel. This module contains a diode that has a high failure rate. The module sends a command to the Daytime Running Lamps Relay located in the convenience center (firewall passenger side).

If you have the latter system, remove the relay and insert a jumper wire across the power terminals. See Relay Layout. If that fixes the problem, replace the relay. If it doesn’t, replace the Daytime Running Lamp Module.

Chrysler updates spark plug recommendation

Rick — Wed, 18 Nov 2009 02:09:23 +0000

Chrysler has issued a TSB #08-008-04 that changes the recommended spark plugs for 2003-04 Chrysler Sebring and Stratus, 2002-04 Jeep Liberty and Cherokee, 2003-04 PT Cruiser, 2003-04 Chrysler Voyager, 2003-04 Town and Country, Dodge Caravan, and Plymouth Voyager vans, and 2003-04 Jeep Wrangle. All of the affected vehicles have the 2.4L engine.

The new spark plug is RE16MC (gap 0.40″). Chrysler also recommends installing a new set of spark plug wires at the same time since old boots can take a thermal set to the spark plug. Once that happens, the high voltage can spill out of the “set” and cause secondary ignition flashover.

No crank, no start – Dodge Trucks, Jeep, Avenger, Sebring, PT Cruiser

Rick — Sun, 06 Sep 2009 01:46:15 +0000

No crank, no start Dodge Trucks and Jeeps

Chrysler has issued a TSB #08-007-08 to address problems with no start, no crank on 2006-08 Dodge 1500-5500 series Ram trucks and 2007-08 Jeep Wrangle, Compass, and Patriot, 2008 Jeep Liberty and Cherokee, 2007-08 Avenger / Sebring, 2007-08 Caliber, and 2006-08 Chrysler PT Cruiser vehicles. The problem occurs most often in dry or cold conditions and is caused by static electricity latching up the keyless entry module. You can “reboot” the module by either disconnecting the negative battery cable or removing the IOD fuse for 30 seconds and then re-installing. But that’s a temporary solution.

The permanent fix is to replace the Wireless Control Module (WCM) with a new style that’s better insulated against static electricity. You can replace the module yourself, but you then will have to reprogram the ignition keys to the new module.

Speedometer needle on wrong side of peg – Caravan

Rick — Fri, 04 Sep 2009 01:03:22 +0000

Drivers may find that the speedometer needle is on the wrong side of the stop peg after charging or changing the battery or cleaning the battery terminals.

You do NOT need to remove the instrument cluster to fix this problem.

Insert the key in the ignition. Then press and hold the trip odometer reset button until you see “Sof” appear along with a software version number (like Sof 3.2). The cluster will then display any trouble codes and when it’s done, the word “end” will appear. The cluster will then initiate a series of tests than include sweeping the needles side to side. When the testing is done, the needle will be on the correct side of the peg.

P1494 EVAP Leak Detection Pump Switch or Mechanical Fault

Rick — Sun, 30 Aug 2009 15:49:13 +0000

To diagnose this problem, follow this procedure:

Turn the key to the ON position. Check for battery voltage on the power supply wire (pink/grey)at the 3-way connector located on the Leak Detection Pump. If you detect battery voltage on more than 1 wire, the wire harness is shorted and must be repaired before proceeding with other tests.

If you find battery voltage on the power supply wire, reconnect the connector. Use your computer-safe test light to backprobe the the LDP “sense circuit” (purple/white) at the connector. You should see power on this wire at key ON. Use a jumper wire to quickly backprobe the purple/blue (solenoid) wire and touch the other end to ground. The test light should go out when the solenoid operates. When you remove the ground wire, the light should go on again. If you don’t get this result, either you have a short to ground in the wiring harness “sense” circuit, or the LDP is bad.

Next, disconnect the connector at the PCM and the LDP and check the wiring harness for a short to ground on the sense circuit.

If all the electrical repairs check out, the problem is a vacuum leak.

Load moaning sound on cold start – Chrysler vehicles

Rick — Mon, 17 Aug 2009 01:37:27 +0000

The power steering reservoirs on these Chrysler vehicles have a fine mesh screen in the bottom. As the ATF fluid breaks down it plugs the screen. The return line from the rack is located right at screen level and swirls the fluid around the screen (see photo). When you start these babies cold, the PS pumps are starved for fluid. They make a terrible (and LOUD) moaning sound. As the PS fluid heats up, it swirls around the screen and gets the sediment back in suspension. There is NO WAY to clean out this reservoir. (I’ve tried). Save yourself the time and aggravation and just buy a new one from the dealer. They’re about $25. Then refill the system with ATF+4 fluid. You have to use a vacuum pump to bleed the air out of the system.

Blower Motor Resistor Location PT Cruiser

Rick — Mon, 01 Sep 2008 04:00:00 +0000

A reader wrote to me asking for the location of a blower motor resistor on a 2005 Chrysler PT Cruiser. Normally I don’t answer specific reader questions (because I really do have a full time job and this blog is my hobby), but they asked so nicely I couldn’t resist (Bad, bad pun).

The blower motor resistor is located under the dash on the right hand (passenger) side. It’s near the firewall, just below the windshield. So it’s pretty high up there. Follow the duct work because the resistor block is always mounted on a duct. It needs airflow to cool it off.
