The code is P420. One 02 sensor was replaced cost for part $226.00
What is the TWC catalytic converter?
Does this code (P420) refer to any particular bank?
Also what do the sensors cost and how many are there?
This one was not from a dealer
You asked for the code in order to reply. Your reply is basically "take it to a repair shop".
What is the significance of code PO420. You refer to numerous sensors such as MAF, crank, IAT etc. That is why I asked how many there are. If the code refers to bank 1 does that indicate that the problem is in that converter or one of two sensors.
As an expert shouldn't you know the cost of a sensor? Is an A/F the same as an o2?
Am I a pain?
GregI did give you a rating.Thanks.The problem was a sensor and an exhaust leak near the sensor.Frank
