What does the p0406 code on the EGR sensor mean?
P0406 means that the exhaust gas recirculation (EGR) sensor A has high circuit voltage. The ECU detects this high voltage and sets a Check Engine Light. The Check Engine Light will be illuminated on the dashboard. What causes the P0406 code? What are the symptoms of the P0406 code?
What does p1406 mean on a Ford engine?
P1406 FORD Meaning The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small amounts of exhaust gas back through the upper intake to get mixed in with the air/fuel charge.
What does the odb2 trouble code p0406 mean?
P0406 is a general ODB2 trouble code indicating a fault within the exhaust gas recirculation EGR circuit. This code is similar to P0400, P0401, P0402, P0403, P0404, P0405, P0407, P0408, P0409. P0406 means that the exhaust gas recirculation (EGR) sensor A has high circuit voltage. The ECU detects this high voltage and sets a Check Engine Light.
What causes a p0406 circuit to short out?
Potential causes of a P0406 code include: EGR sensor signal circuit shorted to B+ (battery voltage) EGR sensor signal circuit shorted to the 5 volt reference circuit to EGR. EGR sensor ground circuit open.

What are the symptoms of the p0406 trouble code?
What are the symptoms of the P0406 code? In most circumstances the driver may not notice any symptoms other that then illuminated Check Engine Light. Some vehicles may have a slight engine hesitation and fluctuating RPMs. In rare cases the vehicle may have some pinging at higher load and engine stalling.
How much does it cost to diagnose p0406 Chrysler code?
The cost of diagnosing the P0406 CHRYSLER code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0406 CHRYSLER code detected?
What does the OBD code p0449 mean?
OBD-II code P0449 will trigger the Check Engine Light to illuminate on the dashboard. However, you’ll need to connect your vehicle to a scan tool to determine if there’s an EVAP system vent control circuit malfunction or a problem with the EVAP system vent valve solenoid.
What does the OBD2 code p0406 mean?
A closer look at OBD2 code P0406 When your car’s computer tells you that there is a P0406 code, then it’s a problem with the EGR sensor A having a high voltage. When the EOM detects that the EGR voltage is higher than the allowed range, the check engine light will flicker on your dashboard. What are the possible symptoms of the P0406 code?
What should the p0406 EGR sensor reading be?
There is a feedback sensor on most EGR valves that informs the computer of the actual EGR position. This sensor usually ranges between .4 and 5 volts If this EGR position sensor has an abnormally high reading for too long, this code may set. Symptoms of a P0406 DTC may include:
What is the p0406 code on a Chrysler 300?
