P1294 Target idle not reached this is the code in the chrysler list of codes for this number and reading it ,it must mean the idle isnt correct when engine is warm but i could be wrong here in my interpretation as our europeon test puts a probe up the exhaust and the idle doesnt come into the equation .So long as the gas output from the engine is below the specified limits on first run at 2500 rpm then idle is read but this is only for the CO and oxygen levels in the exhaust gas as the level of CO2 will depend on the size of the engine but must be below 2% on idle ,so a big monster american gas burner will still be below the 2% by volume on idle but rise with the increase in engine RPM .Complicated business and costly when the cat goes

Code C2100 2008 chrysler sebring what that means my car giving that code


C2100 Engine Fault Code Check Solution For C2100 OBD Code : C2100 engine code seems a kind of chassis problem, we try to show one by one the meaning and the solution.
Brief explanation of the C2100 code and definition of C2100 is the bottom side.

C2100 Meaning :

c Chassis Code
Problem is controller area network wiring bus and modules. 2 MFG - Manufacturer Specific 1 BBV Sensor Circuit Low Voltage 0 Low Coolant Circuit 0 Park/Neutral Postion (PNP) Switch Circuit Engine Torque Signal Circuit MFG - Manufacturer Specific codes, which have a '1' as their second digit to indicate they are unique to a particular vehicle make or model. These special codes were deemed necessary by the vehicle manufacturers so they could provide additional diagnostic information beyond the basic list of generic OBD II codes for all kinds of faults, not just emissions-related faults.

How To Fix C2100 ?
There are currently two main types of cylinder deactivation used today, depending on the type of engine. C2100 code for the pushrod design which uses solenoids to alter the oil pressure delivered to the lifters. In their collapsed state, the lifters are unable to elevate their companion pushrods under the valve rocker arms, resulting in valves that cannot be actuated and remain closed. C2100 Code Description: The oxygen (02) sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions. When you see C2100 engine fault code on your engine code reader this description will help you.
C Codes List of all Chassis codes. Final Step: In the definitions listed below, there is a test drive recommended after you've completed any repairs to see if the condition is fixed. Before you take a test drive after a repair, always erase the C Code(s) first. This will turn the check engine light off and then you will know if the check engine light returns, you've got further diagnostics to complete.

'09 wrx obd codes P2200 and P3700....what do they mean?


P2200 = nitrogen oxide sensor bank 1.
P3700... no clue. Probably related to P2200, but manufacturer-specific.

That's an '09. This is an emissions issue. Your vehicle is covered by an emissions warranty until the year 2019. Use that warranty, don't pay to get this fixed.

Low RPM at idle error code P1294


P1294 WHAT ENGINE? target idle not reached, (means idle is wrong)
4.0L or 4.7L

means the ISC was changed by the PCM (commanded) and the ISC
failed to adjust idle to the correct speed.
clean the throttle bore.
clean the ISC.
or find intake leaks.

see chapter emissions here.
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service


it means IDLE controls are out of control.
only that. and many things can cause that.
lean fuel mixture, gross misfire.
ISC unplugged?
a tech, checks all these things. the engine is running right
and when sure the engine is right, and holds closed loop at idle !!!
then and only then start testing the ISC.
we make sure it can move through its range.
and that the throttle plate is not blocked. for (any reasons)
and then make sure there are no vacuum leaks.
on MAP based systems, any air leak cases the engine to race
and if bad enough the ISC fails to work right. (for sure)
those are the hit lists. the tests are extensive.

2003 Land Rover Range Rover;SES light came on, had it scanned and came back w/code p1453. Can you tell me common symptoms of this code and what a fix may be?


Diagnostic Test Code (DTC) P1453 is a "Manufacturer Specific" code, which means that it is defined only by the manufacturer of the vehicle and does not exist in any standard lists of DTCs, such as the standard SAE J2012 listings.

DTC P1453 for a 2003 Land Rover Range Rover, is defined by the vehicle manufacturer as "DM-TL REFERENCE CURRENT TOO LARGE"

The possible causes listed by the manufacturer are"

> DM-TL Module

Please note that DM-TL is an acronym for "Diagnostic Module - Tank Leak". This is the module that performs the diagnostic testing on your evaporative emissions system.

So, basicly what is happening here, is that the system that was designed to test the system and warn you of an impending failure, is what is actually causing the system to fail.

Did not pass state inspection (vehicle)


First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.
