P-Code SPN FMI Description Possible Cause Corrective Action
P0699 3511 3 Sensor Reference
Voltage C Circuit High
 Problem with 5 V
sensor power supply.
 Check the ECM leads.
 Check for sensor shorts for
sensors using 5 V sensor power
supply by disconnecting all
sensors and then connecting
back one at a time.
 Isolate a defective sensor. While
monitoring the sensor power
supply with a scan tool or
voltmeter, disconnect all sensors
powered from the sensor
reference voltage C power
supply. When the defective
sensor is plugged back in, the
voltage will fall.
 Replace the ECM. Refer to
Section 5.4.

1 Erratic Air Fuel Ratio
 Diagnostic not set.
 Problem with exhaust
leaks or poor HEGO
sensor performance.
 Check for exhaust leaks before or
near the HEGO sensor.
 Check for intake manifold leaks.
 Verify that the HEGO sensor is
installed securely.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
P1135 3217 2 Oxygen Sensor 1 Bank
1 Lean Shift
 Diagnostic not set.
 Problem with exhaust
leaks or poor HEGO
sensor performance.
 Check for exhaust leaks before or
near the HEGO sensor.
 Check for intake manifold leaks.
 Verify that the HEGO sensor is
installed securely.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
P1136 3217 2 Oxygen Sensor 1 Bank
1 Rich Shift
 Problem with poor
HEGO sensor
performance.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
P1137 3217 31 Oxygen Sensor 1 Bank
1 High Impedance
Degradation
 Problem with poor
HEGO sensor
performance.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
P1138 3217 31 HEGO Sensor Overheat
 Problem with poor
HEGO sensor
performance.
 Check for excessive exhaust
temperatures.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
