Ode p 0011 cam shaft overvanced bank one 2006 mustang gt how do you fix it fro being over adanced /


P0011 FORD - Intake Camshaft Position Timing Over Advance Bank 1

Possible causes
Low or Dirty Engine Oil
Incorrect camshaft timing
Valve Control Timing (VCT) position circuit is open or shorted
Valve Control Timing (VCT) position circuit poor electrical connection
Faulty Valve Control Timing (VCT) position solenoid

The "Possible Causes" is the list of all the items, components or circuits that should be inspected, test, repair or replace to fix the OBDII code. AutoCodes.com goal it to help you find the best possible solution to your OBDII code problem. Harness is open or shorted It means that the wire(s) connected from and to the component (sensor, solenoids, actuator, etc.) is either open (cut, broken, disconnected) or shorted (touching other wires, components, body). "Open" and "short" are common electrical terms. An open is a break in a wire or at a connection. A short is an accidental connection of the wire to ground or another wire. In simple electronics, this usually means something won't work at all. With complex electronics (such as ECMs or PCMs) this can sometimes mean something works, but not the way it's supposed to. Wire circuit example: Circuit poor electrical connection It means that the component (sensor, solenoids, actuator, etc.) connector is not fully connected or is disconnected. Before replacing any components, try fully disconnecting the connector, reconnect and test the system or component again. Faulty or Failed component It means that the component it's more than likely the cause of the code, and that needs to be replaced. Engine mechanical problems When "engine mechanical problem" is listed as possible causes of the OBDII code, it means that the problem is not caused by an electronic component, but rather by a mechanical component such as pistons, valves, mechanical pump, etc. Engine Lean System (Lean Mixture) "Engine Lean" or "Lean Mixture" means there is an excess of air during the engine combustion. The ideal Air/Fuel (A/F) ratio is 14.7:1, which means 14.7 parts of air to one part of fuel. Intake gaskets, faulty Mass Air Flow (MAF) and faulty A/F Sensors, are common problems when the engine is running too lean. Engine Rich System (Rich Mixture) "Engine Rich" or "Rich Mixture" means there is an excess of fuel during the engine combustion. The ideal Air/Fuel (A/F) ratio is 14.7:1, which means 14.7 parts of air to one part of fuel. Leaking fuel injectors, bad spark plugs, faulty Mass Air Flow (MAF) and faulty A/F Sensors, are common problems when the engine is running too rich.

Check camshaft position sensor exhaust bank 1.
camshaft position actuator solenoid-exhaust bank 1
camshaft position actuator solenoid ,intake bank 1. camshaft position sensor intake bank 1.

Bank 1 is usually where the number 1 cylinder is located, or left side depending on manufacturer....

What does it mean when it said to lean bank 1


It means that one side of the engine cylinders are running too lean of a fuel mixture Bank one is the left side of the engine. Put a fuel injector cleaner in the gas tank first. Once it has had time to do its work, test again. If it's still lean, then look at the injectors and the control module for a fix.

97 ford expedition has a code 171 and 174 bank 1 and 2 lean what do i do to fix this


Code 171 and 174 are for bank 1 and 2 running too lean. The engine has compensated as rich as it can go, and it is still to lean. This does not necessarily mean your mixture is bad, but something (a sensor) is telling the ECM to correct lean. The oxygen sensors alert the ECM to how lean/rich the exhaust is, and then the ECM trips a code. Maybe you have a bad oxy. sensor, but since there are 4 of them (2 per bank), I don't think they could all go at once.

I have a 2003 ford winstar and the check engine light is on. The code readings say Bank 1 and bank 2 is lean. What does that mean?


It means both O2 Sensors, are reporting a lean
exhaust mixture. An out of range condition, that
set the check light

Now you need to figure out why--vacuum leak etc.

I would guess you need a repair shop, that can
diagnose that issue

Check all the bolts holding the plenum, and anything else concerned with air intake. Too much air means weak mixture.

MY LEXUS IS200 SE engine management light came on had it checked it was sensor 1 bank 2 had it replaced it came on again sensor 1 bank 1 had it replaced it came on again sensor 1 bank 2 HELP!!!!!!


What was the code? lean mixture? If so make sure there is no leak in the exhaust. I have worked on a lexus suv, but it was an 89. It had a lean mixture code. After examination I noticed a exhaust leak which was not apparent at first, there is a section in the exhaust the is very thin, and prone to leakage, causing the lean mixture code.
