I have an 05 International with a 650k mile CAT C13 engine. The truck pulls an empty trailer like it's fully loaded. No power at all. So, I took it to a fella that can read the fault codes. Mine is showing 285-5 thru 290-5 and a 385-4. Yes, all 6 actuators are throwing the same code "Intake Valve Actuator #_ current low (92)". Nov 18, 2015 · P0028 – Relates to Intake Valve Control Solenoid Circuit Range/Performance (Bank 2), with “Bank 2” denoting the side of the engine that does not include cylinder #1. Codes P0027 and P0029 refer to the same problem and fault condition in the VVT or VCS control systems of the exhaust side of Banks 1 and 2 respectively. Engine Oil Pressure Sensor; Engine Oil Temperature Sensor; Coolant Inlet Temperature Sensor; Intake Throttle Valve; Intake Manifold Pressure / CAC Temp Sensor; Fuel Rail Pressure Sensor; EGR Delta P Sensor; LPPO Fuel Pressure Sensor; Intake Manifold Temperature Sensor; Camshaft Position Sensor; Fuel Compensation Pressure Sensor; Fuel Doser Line ... The pressure difference is caused by internal leakage. Internal leaks can be caused by mechanical wear, a leak between valve body and transmission casing, incorrect adjustment of the manual valve index spring. The most common cause however is the pressure regulation solenoid valve. Diagnosis. Oct 24, 2019 · Common problems with intake manifolds include vacuum, coolant or oil leaks, reduced flow due to carbon build-up and issues with the intake tuning valves. In some engines, an intake manifold can corrode or crack causing either vacuum or coolant leaks. A cracked manifold must be replaced if it cannot be safely repaired.

Jan 13, 2016 · The purpose of variable valve timing is to ensure that the valves open and close at the right time to maximize engine performance and reduce fuel consumption. When the VVT solenoid is malfunctioning, the entire system can be compromised, which may result in intake and exhaust valves opening and closing at the wrong time. Jan 13, 2016 · Symptoms of a Bad or Failing Variable Valve Timing (VVT) Switch Common signs include a rough engine idle, the Check Engine Light coming on, and the engine stumbling when climbing hills or under load. Jan 27, 2019 · It was a leaking oil pump which cannot deliver the proper oil pressure to activate the VVT-i system. it had a P0016 code Crankshaft-camshaft correlation. had to check the oil control valve, filter, timing chain, VVT then finally open the oil pump assembly which had internal damage which caused the leak. hope this can help other DIY mechanics.

May 31, 2017 · If the valve sticks in the open position, the oil returns to the suction side of the oil pump, resulting in a low or no oil pressure condition. If the valve sticks in the closed position an over pressurization condition can occur, causing the filter to become distorted or the gasket/seal to dislodge, promoting leakage. What's Wrong with My Reciprocating Air Compressor? The air compressor is a powerful machine that, in today's high-tech world, is used by everyone from auto mechanics to furniture makers, in addition to manufacturers large and small. While compressed air is relied upon for heavy-duty tasks that... Mar 06, 2014 · @Tim submitted a new resource: Caterpillar (CAT) ACERT intake valve actuator wiring replacement - 45 minutes from start to finish If you have a Acert CAT odds are your gonna have a wiring issue with the IVA's at some point in time. The cause is oil getting into the wiring plug thus causing a... The intake manifold tuning valve comes with many possible purposes to help the engine in both performance and drivability. It regulates the pressure between intake plenums, or redirect intake air to separate set of intake runners (or combination) to change the flow and possibly the performance of the engine. May 15, 2011 · The 385-3 is an open circuit on the Intake Valve Actuation Pressure sensor. This sensor is located on top of the engine also and has 3 wires going to it. These sensors failing are very common on C15 ACERT engines.

37 - Intake Air Passage (Electronic Throttle Valve) or ECU Processing Information (OX66) 38 - ECU Processing Information (OX66) 39 - Oil Pressure Sensor 40 - ECU Processing Information (OX66) 41 - Overrev Control During Ignition Cutoff Operation (OX66) 42 - Overheat Control or No Oil Control (OX66) 43 - Buzzer Sounding (OX66) Jan 13, 2016 · The purpose of variable valve timing is to ensure that the valves open and close at the right time to maximize engine performance and reduce fuel consumption. When the VVT solenoid is malfunctioning, the entire system can be compromised, which may result in intake and exhaust valves opening and closing at the wrong time. 157-2 Abnormal oil tank pressure (pump overpressure) When the oil suction control valve power is 40% or more, or when the suction control valve target pressure is 90 mm3/sec or less, the actual oil sump pressure is 40 MPa higher than the target sump pressure ( 410 kg/cm2, 5820 psi)

valve, and the intake piping to the turbo for signs of damage. Inspect all intake system connections and clamps. If an air induction issue is found, repair as required. Possible problems include loose or damaged clamps, damaged connectors, restricted air filter, intake throttle valve stuck closed, and an air intake restricted by debris, rags, or Nov 16, 2016 · During the control module's shutdown phase the diagnostic function monitors the barometric pressure sensor, intake-manifold sensor and the pressure sensor on the air-intake side of the throttle valve to determine whether they are all measuring the same pressure.
