Check engine lite on with PO421 code


P0421 = Catalyst System Efficiency below Threshold(Bank1) The catalyst's efficiency is demonstrated by its ability to oxidize CO and hydrocarbon emissions. The Powertrain Control Module (PCM) compares the output signals of the front and rear oxygen sensors to determine whether the output of the rear sensor is beginning to match the output of the front oxygen sensor. Air/fuel mixture compensation keeps the frequency of the front oxygen sensor high due to the changes from rich-to-lean combustion. The catalyst causes the rear oxygen sensor to have a lower frequency. As the catalyst wears, the rear oxygen sensor's signal trace begins to match the front oxygen sensor's signal trace. That is because the catalyst becomes saturated with oxygen and cannot use the oxygen to convert hydrocarbon and CO into H???O and CO??? with the same efficiency as when it was new. A completely worn catalyst shows a 100% match between the frequency of the front and rear sensors.

I recieved a code PO139 on my Hyundai Elantra and was wondering what that code details. Thanks


P0139 - HO2S Circuit Slow Response (Bank 1 / Sensor 2)

Possible causes:

Leak in intake or exhaust system
?? Faulty fuel system.
?? Front and rear HO2S connections reversed.
?? Contact resistance in connectors
?? HO2S contamination

Most PROBABLE cause: Defective/Old/Aging O2 sensor

The code is p1125bb


Diagnostic Test Code (DTC) P1125 Has to do with your Accelerator Pedal Position Sensors (APP).

The APP sensor 1 and APP sensor 2 are potentiometer type sensors with the following circuits.
• A 5-volt reference circuit
• A low reference circuit
• A signal circuit
The APP sensor 1 signal to the PCM is low at rest and increases as the pedal is depressed. The APP sensor2 signal also low at rest and increases as the pedal is depressed. DTC P1125 sets when BOTH of these sensors have a problem. It will not set if only one of the sensors are not reading correctly. This code also does not set alone. There will be at least 2 other APP fault codes set along with this code and these codes MUST be diagnosed first.

Jeep charokee has no engine fire,check crank position sensor it was loose wires were fraid i replaced sensor still no fire


Hi there,

Firstly, you need to extract your vehicle's diagnostic codes - this will identify where the problem lies.

Instructions (using ignition key method):

Codes are shown by the Check Engine Light (CEL) on the dash. 1. Turn the ignition ON-OFF, ON-OFF, and finally ON again (without starting) 2. Codes will be emitted via CEL on the dashboard display. 3. Read codes as described below. Reading codes: Each code consists of two groups. The first group of flashes indicate the 'tens' digits. The second group of flashes indicate the 'ones' digits. A short pause separates 'tens' and 'ones' digits. A long pause separates each trouble code. e.g. Long flash, Long flash (short pause); short flash, short flash (long pause).....then repeats... The above flash sequence indicates Code 22. If you are able to get your codes, post them here and I can assist you further. Cheers, "If this has helped you in any way, please place a testimonial"

We just fixed the EGR valve and now 3 weeks later the P2097 error code was detected.


Not sure of your vehicle but it is not likely that it's part of the EGR valve although you need to make sure the gasket for the EGR valve isn't leaking because leaking exhaust will set this code. Does your vehicle have a EGR solenoid/transducer. The reason I ask is because in Chrysler products the EGR valve and transducers are calibrated together and this may be causing the EGR to open to much and exhaust will leak. I serious don't that it has anything to do with the EGR valve you just replaced however. I think you just have another problem. That's my opinion anyway. The possible causes of the code is: • Leakage exhaust gas • Rear HO2S malfunction • IAT sensor malfunction • ECT sensor malfunction • Front HO2S malfunction • Excessive fuel line pressure • Fuel pump unit malfunction • Purge solenoid valve malfunction • Insufficient engine compression • PCM malfunction Find out about the transducer and then go from there like O2 sensors as well as the other possible causes. I wish I could be more help and I hope this helped a little anyhow. Good luck.

There is a diagnostic code P1625 for 2001 Saab 9-3 convertible with 88,115 miles. Is this an expensive fix?


P1625 means that the engine computer has lost communication with the antilock brake and/or traction control computer for at least 3 seconds. How expensive this is depends on why it has lost communication, It could be something as simple as a loose connection at a wiring connector or a broken or shorted wire in the PCI bus circuit inside the wiring harness. (Which may require considerable diagnostic time to find) or it could be an internally failed ABS module.

Recommendation:
If you are NOT experiencing ANY of the symptoms below, I would simply clear the code and move on.... It is an intermittent fault that you will most likely not find very easily. If you ARE experiencing ONE OR MORE of these symptoms, then the problem needs to be diagnosed by checking the ABS module's ability to communicate with a scanner while testing the PCI Bus circuits.

Other possible symptoms of Diagnostic Trouble Code (DTC) P1625
• Speedometer malfunctioning
• Traction Control malfunctioning
• Antilock Brake System malfunctioning or ABS light on
• Cruise Control malfunctioning

I can't change from park to drive, my mechinic said that the gear cable has broken is that true and how much should it cost to fix


If this was seen by your Tech then it can be right as the links are not working. The cost of the cable might not be much than to change the cable which is at the discretion of the person who can give you a discount.
Standard company charges may vary but you can get an estimate.
check spares price from these links;
