P1401 - DPF EGR Sensor Circuit High Voltage Detected The EGR monitor checks the DPFE sensor signal to the PCM for high voltage. The test fails when the average voltage to the PCM goes to a voltage greater than the maximum calibrated value.
Possible causes:
DPFE circuit open
VREF short to PWR
Damaged DPFE sensor
DPFE circuit short to PWR
SIGNAL RTN circuit open
Damaged PCM
Look at scan data stream for a reading greater than 4.5 volts with the key ON and engine OFF or running. This indicates a hard fault.
Possible, but not likely.
It is possible but not likely.
The trans is electronically shifted so the sensor being bad is a likely cause.
P0073 is Ambient air temp sensor high. Likely cause is the sensor itself.
The transmission computer takes the output speed sensor signal and sends it to the cluster for the speedometer reading. The output speed sensor is a likely cause.The transmission computer takes the output speed sensor signal and sends it to the cluster for the speedometer reading. The output speed sensor is a likely cause.
Problem with Knock Sensor circuit #1
Check the distributor. That is the most likely cause, or the crankshaft sensor.
Not likely. Code P0138 is------O2 Sensor Circuit High Voltage (Bank 1 Sensor 2).
It could be your MAF sensor. Mass air flow sensor that measures the air going into the intake. This could likely cause sluggish acceleration.
Most likely cause is a faulty coolant temperature sensor.

Not likely but possible. I would suspect a leaking vacuum hose.
