Long story. I swapped a California ECU into my Federal 2000 limited 4runner. The truck seems to run fine, but is throwing a code for a sensor (I think P1130). Is this because of the ECU or is the sensor bad? Anyone done this? Would this problem be fixed by placing a spacer on the rear sensor?

You must have great Luck the fact it runs at all is amazing

To figure out your problem your going to need to sit down and compare the 2 different ECM`s see if one of the pins or more need moved

You are getting a P1130 (A/F Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1) because the ECU is seeing a standard O2 sensor and it wants a widerange air/fuel sensor. You are probably stuck in open loop, where the ECU ignores the front exhaust sensor and uses a stored map. MPG and performance will be degraded.

You can try wiring in an A/F sensor (plug for O2 sensor will not fit). In theory, it should work.
