SOURCE: Engine light came on. The dealership said it was diagnostic code P0420 and that it would cost @ $1,200.00 to repair. This seem pretty high. What is this diagnostic code about and is the repair rate

Hi, this code represents a Catalyst System Efficiency Below Threshold (Bank 1). and the repair, considering that it will be repaired by the dealership, seems to be in the normal cost range. The labor is what usually inflates the price when dealing with catalytic replacements.

You could probably get a better deal by taking it to a non dealership type of repair shop. This may cut at least 200 dollars of the original dealership quote.

Please rate and god bless:)

SOURCE: check engine light on,running rough code P0172

When I see all these codes i instantly think of two things. Vacuum leak especially intake manifold gaskets and Mass air flow sensors. Spray the engine with carb cleaner when its running and see if you get it to rev up,run rough or run different. Next unplug the MAF and drive the car, see if it runs normal.

I replaced an oxygen sensor in my dodge stratus twice..the check engine light came back on and the code says it's the same sensor..what do you suggest


The problem with a code read is that it IS NOT the same as a diagnostic. The reason for the O2 sensor code is obviously still a problem. If the code was for a lean condition (for example P0171) then the O2 may have been doing it's job and the engine really is running lean from other reasons -- like a vacuum leak or poor air fuel mixture. If it had a code P0172 = that is code for a rich condition... Still the O2 may be doing it's job and the engine is really running rich. You really need to see O2 data to determine if the O2 is at fault and also need a technician that is well versed in diagnostics to read the scanner.

I would suggest taking the vehicle to a qualified technician to be diagnosed and then replace the necessary defective item(s).

Speedometer sudenly stoppped working. now works intermittently. also shows check engine light. It is showing p0171 & p0172 codes. Lean and rich. seams like they contradict each other. occasionaly the...


P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks.Replace MAf sensor,if cleaning the MAF does not help.
OBD II P0172 Fuel System Too Rich (Bank 1).P0172 - System Too Rich (Bank 1) Essentially this DTC means that an oxygen sensor in bank 1 detected a rich condition.
When the code says that the Fuel System is "too rich," it means that the computer has been subtracting more and more fuel, which is called Long Term Fuel Trim. Ideally, the Long Term Fuel Trim should be close to 1 to 2 percent. When a code P0172 is set, it means that the Fuel Trim is anywhere from -15 percent to as low as -30 percent compensated. When this happens, the computer knows that there is an improper condition in the control of the Fuel System.


Thanks.
