If you look in the middle schematic there is a fuel pump relay with no wires going to it.

02 duramax rail pressure sensor wiring diagram. Take that reading from between the center wire yellow and ground Tan. Replacement restores engine performance. Fuel Pressure Sensor for 01-04 LB7 66L Duramax Genuine Bosch Part 0281002398 OE 97329566 Fuel Pressure Sensor effectively measures fuel pressure in the fuel rail alerting both the EVAP system and the fuel system to leaks.

Case1 49 Failure out of 50 sample Case2 49 Failure out of 50 sample A P0089 Rail Pressure sensor. This is a very common problem that we hear about from our Duramax customers. Locate the manifold absolute pressure MAP sensor.

4 Connect the 3-pin connector that matches the factory Fuel Rail Pressure sen-sor connector into the factory Fuel Rail Pressure sensor. Ls1 Oil Level Sensor Wiring For Swap Clarification Ls1tech. It has a fuel injection control module and a fuel rail pressure regulator and an injection pump.

The rail pressure sensor is made from a semiconductor and uses the Piezoelectric Resistive Effect to detect changes in electrical re-sistance based on the pressure applied to the elemental silicon. This information is sent to the engine control module ECM to assist in the fueling of the engine. Lly Duramax Egr Pipe Heater 97365034.

Under full load do you notice pressure dip from 26000 to below 20000 is that the rail relief dumping. Figure 2 - Rail Pressure Sensor Connector Orientation 4. Once the fuel rail pressure sensor wire harness connector has been disconnected plug the fuel rail pressure sensor pigtail wiring harness into the sensor.

6 6l Duramax Turbocharger Removal Procedures Step By Step Lly. This harness eliminates the need to cut splice or modify the stock harness when installing a rail pressure gauge by connecting. Pressure Wiring Diagram Daily Update Wiring Diagram.

6 6 Duramax Cooling System Diagram. 32 Rail Pressure Sensor The rail pressure sensor detects fuel pressure inside the rail and sends a signal to the engine ECU. It is a three wire sensor that provides an analog voltage signal.

You should get 5 volts from 5 Volt reference to ground. In comparison to. It is primarily used for diagnostic purposes in the first LB7 Duramax engine.

The PPE Diesel Fuel Rail Pressure Gauge Harness 513010100 make installing a PPE Fuel Rail Pressure Gauge into your 2001-2010 GM Duramax LB7LLYLBZLMM or 2003-2017 Dodge 59L67L Cummins a plug and play installation. Sensor Fuel Rail Pressure FRP Too High Rail pressure should be higher than minimum commanded rail pressure minus possible transitional undershoot Case1 rp 167MPa Case2 rp 190MPa No related malfunction RPS_LO RPS_HI 5VB_A not in Power_Down_Mode Rail Pressure Feedback Mode Key_on_time0125 Sec. The Pressure Signal is from the center wire.

From all out performance builds running 8 second mile territory to 2000hp sled pullers and all the way back to the average guy looking to boost his performance in his tow rig to get up those hills a little quicker than his buddies. 08 lmm efi live BMW5in afe exhaustmbrp downpipe afe intake afe turbo inlet pcv reroute rail plug sdp egr delete sdp y bridge ppe manifolds uppipes fass 150 beltech 3 shacklesisspro pyro boost and rail pres gauges22 in XD Monsters wrapped with Nitto 420s. This should fit in the same orientation as the connector you just removed.

Lly Engine Diagram Wiring Schematic Diagram. LB7 left and LLYLBZLMM right 5. Actual fuel rail pressure is not keeping up with desired fuel rail pressure.

Fst800 1100 Cheap 0 10bar 16 Bar Mems Gas Small Water Pressure. Those are the two outside wires on the sensor. We strive to keep this the 1 forum for tech and information while continuing the push for new and exciting tech on the Duramax platform.

Route and connect the green signal wire from the gauge wiring harness directly to the green signal wire of the pigtail harness. It operates the fuel supply system by vacuum. The FRP sensor uses a 5-volt reference circuit a signal circuit and a low reference circuit to monitor fuel rail pressure.

Route and connect the black ground wire from the gauge harness directly to the black ground wire. Low rail pressure may or may not cause an MIL check engine light. Remove some of the wire shroud from the MAP sensor wires to expose the wires that run into the MAP sensor connector.

A Infi Ltrometer Stand And B Schematic Wiring Diagram To. C4500 Duramax Engine Diagrams Wire Management Wiring Diagram. This video is an extract of the AutoMate FRPS Signal Voltage Low Pull Up Type diagnostics training videoThe extremely high fuel pressures that Direct Inject.

Connect the factory Fuel Rail Pressure connector to the molded plastic connector on the supplied wiring har-ness. Figure 3 - MAP Sensor Locations. It operates on around 30000 psi.

Dhd 700 011 Lb7 Duramax Low Pressure Oem Fuel Line Kit. While cranking it should work its way to about 11 Volts which is 4000PSI. Be VERY careful when working on the high pressure side of the system.

ECM uses feedback from the sensor to adjust turbocharger vane position to deliver desired boost. This may only happen in high fuel demand situations like towing or racing but it can also happen with everyday use. Since the LLY Duramax the manifold pressure sensor has been used almost exclusively for turbocharger control.
