Good Day, I have an 06 Jeep CRD, Throwing a P0299 low boost code. I could really use some help. Has anyone ever encountered this problem: - It struggles to make RPM under no load, even at idle - Low Boost code on scanner even under no load condition I have been working on this for months and have checked and/or repaired the following with no change to main complaint. I live in the Virgin Islands with no access to a certified Chrysler dealer to run diagnostic. WE have steep grade hills and the vehicle must make power starting on a hill. I bought the vehicle and had it shipped here. It had a multitude of diagnostic codes and running problems that I have worked through and repaired. The vehicle cannot be used at all in its current state. The Following has been done: - Changed CAC hoses -Sasquatch stage 1 EGR delete and Green Diesel Eco Tune - Changed turbo Charger and actuator - Both vacuum control solenoids and vacuum modulator - Test and changed all Vacuum hoses and checked vacuum reservoir. Final INHG at vacuum modulator control outlet is 13 INHG -Changed timing belt, rocker arms, crank case vent bypass, new K&N intake, new accelerator peddle, inline electric fuel pump, fuel filter base & heater plugs upgraded, map sensor, fuel quantity solenoid, fuel pressure sensor, tank pick-up, fuses and relays, - Fuel Flow test- no air in line, - Checked harness for chafing behind fuel filter housing connections and grounds. -Installed manual boost gauge which shows 22lbs on flat road, but when encountering hills cannot calibrate for load and drops down between 0- 5lbs - Shows no heavy smoke or misfire - Problem persists regardless of stock or eco-tune - Leak down tested charge aircooler and intake system, intake manifold has been completely cleaned |

I got this code recently, It turns out that the clamps had worked themselves slightly loose on my CAC hoses, and I also bled the fuel head for air. I then deleted the code, and it hasn't yet returned. IDK if this will help you... |

No leak down tested several times already. Does anyone know how to test ecm signal to the boost modulator? |

Yes when I first recived the car it was in third gear limp mode. Transmission DTC code for transmission fluid temp sensor and electric fan remained on. I did a complete servuce of transmission and tested the sensor. It was ok. I put everything back together and replaced the TCM relay and dtc code cleared and has not been a problem since. So.ething I did notice with the transmission is when GDE eco t u ne software is installed I get a terrible vibration from the transmission when in gear, intermittently. If I flash back to stock it does not do it. I also often find the transmission dip stick pushed up two inches out of the dipstick tube after running the car. Vibration does not exist with transmission in park. |
