Attention: TDR Forum Junkies Lately I have had a problem with low boost at low RPM that throws a PO237 code. Under light throttle acceleration the boost pressure seems to take a while to pass 5PSI and the Check Engine light pops on with the PO237 code.
I've replaced the MAP sensor and checked all the connections to the Edge Comp box. I also checked all the turbo hose connections. . all were tight.
It only seems to happen under light acceleration below 1500 RPM. The truck has 107K and I also recently replaced the lift pump as a preventative item.
Any ideas, gang ???
