I am getting check engine sign with codes for all O2 sensors. Is it possible for all of them to go bad at the same time?
Dodge charger 2006 hemi
P0032 -02 sensor Bank 1 Sensor 1 heater circuit high
P0038 -02 sensor Bank 1 Sensor 2 heater circuit high
P0052 -02 sensor Bank 2 Sensor 1 heater circuit high
P0058 -02 sensor Bank 2 Sensor 2 heater circuit high
For all the 02 sensor to go out at one time. Dodge has a service bulletin for this condition TSB # 08-034-05. Titled Engine control Mil on / mulitple 02 sensor DTC set. What this TSB does is reposition the upstream 02 sensor connector and replacing the wiring harness connector and 02 sensors as necessary. It also addresses the cowl drain of water flowing into the connector (for the rear 02) at the center of the rear engine
Here is a partial copy of the TSB
The condition may be due to the cowl drain flowing water onto the connectors for the 02 sensor(s) at the center rear area of the engine. This leads to water intrusion into the wiring harness connector(s) which may lead to terminal corrosion and/or MIL illumination.
DIAGNOSIS:
NOTE :If the vehicle is equipped with a 5.7L engine (sales code EZB) and was built on or before August 18, 2004 (MDH 0818XX), perform Service Bulletin 18-031-04 REV A as necessary before continuing with diagnosis. For 2.7L and 3.5L engines continue with the diagnosis.
