Sais Limp mode

Have a 2010 tundra with 130000 mile . Hewitt bypass kit installed with Hewitt sensor bypass. Check engine light is on trac cntr light stuck in limp mode installed new ecm immediately went into lamp mode check engine light came on in traction control light came on after jumping pins four and 13 with a paper clip for 30 minutes to program new ECm . Haven’t been able to get the truck out of limp mode since installing bypass kit and ecm .

 

Why was the ecu replaced? What fault codes is it throwing? Have you cleared the codes and do they come back? Is the bypass kit wired correctly and was the correct kit installed for the year and faults you're having?

 

What are getting for ODB-II codes? Hewitt bypass requires additional add-ons for the following ODB-II codes.

P2431 – Air Flow / Pressure Sensor Circuit Range / Performance Bank1
P2432 – Air Flow / Pressure Sensor Circuit Low Bank 1
P2433 – Air Flow / Pressure Sensor Circuit High Bank 1
P2436 – Air Flow / Pressure Sensor Circuit Range / Performance Bank 2
P2437 – Air Flow / Pressure Sensor Circuit Low Bank 2
P2438 – Air Flow / Pressure Sensor Circuit High Bank 2
P106B – Pressure Sensor Correlation / Evap. Pressure Sensor
