P0340 code means "Something" is wrong in the timing...
from CMP (Camshaft Position sensor) to the crankshaft bolt.

Very first thing, verify connectors are clean and shiny.
clear all codes, even hard codes.

SOURCE: 1998 mazda 626 check engine light flashing

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. A technician will have to perform further testing to pinpoint cause and the proper repair. When the light starts flashing the computer is telling you to have the vehicle looked at now before other problems happen.

SOURCE: Check engine light intermittently flashing, car jerking.

Could be fuel or electrical related. Since you may not know the history, this may take a while.
Any amount of smoke from exhaust? White, Blue, Black?
Start with most obvious and inexpensive:
1. Fuel filer clogged (replace fuel filter).
2. Could be the ECM (Electronic Control Module). It controls the ignition spark timing.
A few other things... consider other expert solutions...

Abs light stays on and the esc indicator light also but when you start it it shows it off

it resets each drive. the opr guide says that, and does.
its a very complex system, you should RTM.

ill quote your missing pages.
ABS:
If the light remains on after start-up or comes on and
stays on at road speeds, it may indicate that the ABS has
detected a malfunction or has become inoperative. The
system reverts to standard non-anti-lock brakes.
ESP:/TCS
The ESP/TCS Indicator Light (located in the instrument
cluster), starts to flash as soon as the tires lose traction
and the ESP system becomes active. The ESP/TCS Indicator
Light also flashes when TCS is active. If the
ESP/TCS Indicator Light begins to flash during acceleration,
ease up on the accelerator and apply as little throttle
as possible. Be sure to adapt your speed and driving to
the prevailing road conditions

The engine falters at low speeds


The flashing engine check light means a code is being stored in the computer. You need to have this code read and this will tell you what system is malfunctioning.

TCS is a separate issue from PCM code. I would disconnect the plug from PCM and clean with contact cleaner. Most of the times humidity creates corrosion on the pins.

I have the code p0340 for slip n tcs is telling me is a sensor but it show2


I am not sure what "slip n tcs" means but on the 2005 nissan maxima the code P0340 is for the camshaft position sensor circit on bank 1, which is in the rear of the engine compartment. Code P0345 is for camshaft position on bank 2, which is in the front of the engine compartment. The images show the Cyl banks and a cam sensor.6_29_2012_3_38_07_am.gif6_29_2012_3_40_48_am.gif

The TCS light came on and the car started jerking especially at stops. The light would go off for a while after restarting the car but the same problems would happen and the light would eventually come...


The TCS stands for Traction Control System, I believe. The TCS is controlled by inputs from the wheel speed sensors. If you have a bad sensor, then a new hub may be required to repair it.

The check engine light may be a sepawrate problem. Have the codes scanned for both the Anti lock braking sytem, TCS, and the check engine light.

Sometimes it will require a separate scanner for the TCS/ABS vs. the Check Engine light.

Good luck on this diagnosis and repair.

99 TL engine roars and shakes when pressing on gas.


a flashing chack engine light means you have a catalyst damaging misfire the tcs light comes on because this system will not function with certain codes stored for the engine or trans. knowing that you have a misfire you very well could have a bent valve the question is why. have someone check the engine timing incase the timing belt tensioner has failed. i have seen this happen on the 3.2 before or a burnt exhaust valve . as far as the distributor goes the 99 tl does not have one it has cop (coil on plug ignition) . this means you have a seperate coil on top of every plug one of these could have failed check the code to see if the problem is isolated to 1 cylinder rhen start looking at that one and you better hurry that light flashing means you will damage the catalitic converter if the car continues to skip good luck and i hope this helps you.

Tcs light flashes


if you're flooring the car and there's wheelspin that will activate the tcs, which stands for traction control system. It cuts fuel to slow you down until you gain traction. So no burnouts on the TL. =D

TCS/SLIP & Check Engine Light Warning


TCS is Traction Control System,and all TCS's are controlled though the Anti Lock Braking (ABS) system.Here's how it works:Each wheel,or in some cases,only the drive wheels have a speed sensor mounted near the hub or axle,and sends a speed signal to the PCM (Powertrain Control Module).The PCM monitors wheel speed continuously,and if it sees a speed out of the ordinary,say for example the right rear tire is spinning and traveling at a much higher speed than the left rear,the PCM will pulse the brakes through the ABS system on the right rear to slow down the right rear so that the left and right wheel speeds match up,this is how the traction control works.So,if you have a TCS problem,the PCM will see this and set a Dignostic Trouble Code (DTC).You need to pull the DTC's out of the system with a scan tool,diagnose and repair the DTC's.It could likely be something as simple as a malfunctioning wheel speed sensor,but you won't know until the codes are pulled out,as this will point in the general direction.Good luck.
